I LITERALLY HAVE A MATH TEST ON THIS TOMORROW AND MY TEACHER SAID THAT I SHOULD ALREAY KNOW THIS AND REFUSED TO HELP ME. YOU SAVED MY LIFE THANK YOU SO MUCH!
in case the teacher explained it once and you didnt pay attention then do next time, if its otherwise then your teacher sucks, thank god for the internet and be one step ahead of them
@@frmo11. Then you probably didn’t write it down, that’s not a crime but it shouldn’t become a habit or else you’ll always have to spend more time trying to understand what they taught you again
it's different when you are learning in the classroom and learning by your own watching the video. there is no distraction here, while in the classroom there are lot thing that kills your focus. not trying to defend your teacher, but most people learn something much easier when they are 100% focus
I used to be really good at math, but since online classes have started i have gotten lazy and brain became foggy and now i cant solve math problems as efficiently as i used to but thanks to this video,i learned that i still can solve it even if it took me 8hrs of finding the correct youtube video just so i can follow my teachers formula and way of solving. Thanks Sir, truly grateful for people like you. Love from the PH
This is so helpful! I'm not feeling very well the day before my math midterm and can't be bothered to dig through all of my notes trying to find this.. thanks a bunch!
OMG in in 7th grade in Canada about to do my ministry exams for the government and I never understood this thank you so much I might have a chance of passing now
I just wanna say that most of the videos that I've seen have been people that I have observed being left-handed. These kinds of videos have helped me well, and they seem to always know math better! ?
And to find the plus 4 3:14 you must find the 0 term value by substracting the first term value with the commun difference so 7 -3+=4 which equals 4 and so we need to make a algerbaric expression that works with the constant which is 4 and the coeficient which is 3 and make an algeabric expression by using a algeabric letter
Thank you!! This was really helpfully when I was trying to understand rules in sequences and patterens for my Maths exam. Why didn't my teacher teach this way? This was way easier to understand and way quicker!
Well you take the answer of the multiplication before the modification, and subtract/add whatever number is needed for the number that you need to make that formula true
My name is George Clooney !!! i am very grateful sharing this great testimonies with you, The best thing that has ever happened in my life is how i win the lottery. I am a woman who believe that one day i will win the lottery.finally my dreams came through when i email Dr Mofar. and tell him i need the lottery numbers. i have come a long way spending money on ticket just to make sure i win. But i never know that winning was so easy until the day i meant the spell caster online which so many people has talked about that he is very great in casting lottery spell, so i decide to give it a try.I contacted this man and he did a spell and he gave me the winning lottery numbers. But believe me when the draws were out i was among winners. i won 105,000,000,00. (ONE HUNDRED AND FIVE MILLIONS DOLLARS) Dr. Mofar i truly you are the best, with these man you can will millions of money through lottery. i am so very happy to meet these man, i will forever be grateful to you.

I wish i have a teacher like you..A teacher that not strict to the formula and let the student understand in the way that is easier instead of keep remembering the actual formula
I just learned this today in school and I didn't understand anything. I searched this up to help me with my homework. It really helped me understand. Thanks a lot!
BRUHHH I JUST DID A WHOLE AVID TUTORIAL IN THE MORNING FOR THIS AND NOW I SEE THIS IN MY RECOMMENDED LITERALLY THANK YOU I HAVE A MATH TEST TOMORROW ON TOP OF FINALS IN 2 WEEKS
Same but I still don’t understand this recursive and explicit shit if anyone knows what that is I would be great-full as my math teacher is about as good at teaching math as he is at being enthusiastic about teaching math
duuudeee thank you soooooo muchchhhhh i didnt understand anything in school until now u r amazing man HELLLLPPPPEEEDDD MMEEEE SOOO MCUHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
this video was amazing i wish my math teacher teaches like this i can barely understand him because of his accent and just in general he teaches way to hard! thank u so much
***** Yes. The formula for 3, 9, 27, 81 is 3^x, which means "3 raised to the power of x". The first term is 3, the second term is (3)(3), the third term is (3)(3)(3), the fourth term is (3)(3)(3)(3), etc. To get the answer for the 10th term you would have to multiply ten 3's.
the sequene is called geometric progression. Here the common ratio between any two successive terms is same. for ex, 9/3=3; 27/9=3 and 81/27=3, so to find the nth term the rule is a(r)powered by (n-1); here r= common ratio , n is the required term a is the first term of the sequence
I learned this by doing-> The Nth term's #= 1st Term + (Nth term -1 x "reason") that would be An=A1+(n-1 x r). (r) Reason would be the number you're adding to continue the sequence. Ex as the one in the video: (7,10,13,16,19...). To find 100th term using An=A1+(n-1 x r) A100=7+(100-1 x 3) A100=7+ (99x3) A100=7+ 297= 304
I did that way quicker Same sequence Sequence 1; 7,10,13,16,19,.... /\ | Is 3 times table +4 Sequence 2; 3,6,9,12,15,.... See sequence 2 is the same as S1 (sequence 1) just S2 is -4 less So you do 3 x 100 = 300 + 4 (from the 3 being in the 3 x table S2) and the total is 304 :D

Thank you!
Iol :-) you're talking to truth bro he's gifted to be a math teacher
My skills have been blessed
I have been struggling to understand this, and you explained it is a very simple and good way. Thank you so much!
You’re my brothers teacher-
He told me his teacher has a TH-cam channel and-
I found it lol-
why doesn't my math teacher teach like this
Karrieann Olson haha. U wright
Friends I found a formula to win a lottery at tinyurl.com/y8exv43j all you friends should try it….
My math teacher doesn’t do nothin all she does is put her ass on the chair and sleep 💤
Your teacher is controlled by sharks that don't want you to know, so they're kids, friends, relatives know more than you...
You were wright, the machine wrought,kkkkk
didn't understand anything for my test until I saw this
life saver!

I am so glad I could help!
I wish my teacher tought as well as you did. My teacher thinks we already know this and teaches everything lazily
I'm glad I can help!
Hamburgo lol
Same for mine he goes through it to quickly
that's my teacher lol
Ur teacher probably thinks that ur smart
Thank you for posting this. I wasn't in a learning mindset when my teacher went over it.
Explained very well. You’re a great teacher!
This is so helpful! I'm not feeling very well the day before my math midterm and can't be bothered to dig through all of my notes trying to find this.. thanks a bunch!
Omg u saved my life. I'm revising for Mocks and we didn't have great teacher for the past 2 yrs so we didn't know the basics, thank you.
omg thx aloooooot i had a progress test tomorrow and i didn't understand but u saved me thnx aloooooot
OMG in in 7th grade in Canada about to do my ministry exams for the government and I never understood this thank you so much I might have a chance of passing now
did u pass lol?
MY teacher was giving me this and I never know what to do believe me when she sent this video I learnt every thing I needed to get the work correct
I just wanna say that most of the videos that I've seen have been people that I have observed being left-handed. These kinds of videos have helped me well, and they seem to always know math better! ?
I was sobbing because I have a math assignment due at 12. Your a god send, THANK YOU
And to find the plus 4
3:14 you must find the 0 term value by substracting the first term value with the commun difference so 7 -3+=4 which equals 4 and so we need to make a algerbaric expression that works with the constant which is 4 and the coeficient which is 3 and make an algeabric expression by using a algeabric letter
A true life saver sir. I commend you on your dedication and I truly appreciate you knowing about what you are doing sir. Thank you! ;-)
I'm glad I can help! Thanks.
Thank you for the amazing explanation. It was straight forward and quick and not in a confusing way,
Great way to identify a sequence and explain what an algebraic expression is!
If all my math teachers had had your patience and methodology, math would have been a wonder, not a nightmare.
thank you! that was so well explained.
OH MY GOSH THANK YOU!!! I thought this was a complicated lesson but you made it so much easier to understand! THANK YOU AGAIN!
Thank you, you really make this seem so simple and easy!This helps me a lot.
Thank you!! This was really helpfully when I was trying to understand rules in sequences and patterens for my Maths exam. Why didn't my teacher teach this way? This was way easier to understand and way quicker!
thank you so much, my teacher sort of taught us to “guess”. .you’re awesome. i knew there was a simpler way, thank you.
Very wisely and easily explained.
My concept wasnt cleared from book...finally glad...thnkx
its been 9 years and your still saving lives
but how do you know to try adding or subtracting 4 for the formula like i'll probably take forever to find out
Well you take the answer of the multiplication before the modification, and subtract/add whatever number is needed for the number that you need to make that formula true

Thanks for such a nice lesson I really like the way you were explaining I wish that my teacher also teach like you
the most great teacher of all. I wouldn't be surprised if you became a maths teacher in oxford or harvard if you live in America
Thank you so much for the perfect explanation, I had to help my 11 year old daughter with her homework and this helped me immensely.
Ty man my exams are coming and i needed to learn this haha tysm
I wish you were my teacher !! This video helped me a lot. I understand it now, I just need a little more practice. Thank you so much 😊
Help mi bro
I wish i have a teacher like you..A teacher that not strict to the formula and let the student understand in the way that is easier instead of keep remembering the actual formula
God bless you sir! You explained it soooo well. Thank you for this!
My math teacher confused the hell out of me. Thank you for this!
thank you helped alot, do you know how to do this but in a recursive form?
Reksive
I just learned this today in school and I didn't understand anything. I searched this up to help me with my homework. It really helped me understand. Thanks a lot!

wow that is so funny the same thing happened to me
Same but I still don’t understand this recursive and explicit shit if anyone knows what that is I would be great-full as my math teacher is about as good at teaching math as he is at being enthusiastic about teaching math
Finally find this formula that I've been searching for 2 months
THANK YOU SO MUCH !!!! I learned more in 7 minuets than in an hour lesson :)
duuudeee thank you soooooo muchchhhhh
i didnt understand anything in school until now

Dang I'm watching this in 2020 when it was posted five years ago.
9 years
I cannot thank you enough! You've taught me what my teacher failed to do so. Thank you so much!
Happy to help!
Thank you so much! This is going to help me in my exam! Much appreciated!
u explain very well. upload/post more examples please!
Saved my life and grades! Thx so much
THANK YOU! 8 years later this saved me.
Man ur a life saver thanks for clearing my doubts.
what if the first difference is not the same? how will you compute for the formula?
Celine Aquino you see what it goes up in and then use that as if it was your sequence. if its still not the same difference keep going until it is
Yes..
Thank you so much Sir, now i understand :-)
wow I love your teaching methods thank you God bless
I'm literally on the way to my math quiz and could not understand this for the life of me all week. Thank you!!
what if the sequence is not all the same difference apart and you would have to do a second difference
Ikr
I am sharing this RIGHT NOW.!!!
My teacher never got that trick how did you get it
this video was amazing i wish my math teacher teaches like this i can barely understand him because of his accent and just in general he teaches way to hard! thank u so much
THIS IS SO HELPFUL, IM STARTING MY END YEAR EXAMS TOMORROW, THANK YOU SO MUCH.
Holy crap, u explain better than my TEACHER
My math teacher claims she has been teaching for 15 years but i learned my days math hmwork in like 7 minutes
thx for putting this up i was struggling with my homework u made it really clear for me
i never comment on these vids but im not gonna lie this was SO useful and i learned exactly what i needed within 3 minutes thank you
Glad it helped!
Really helped, Thank you! But i really have trouble finding the formula for this sequence: 3,9,27,81
***** Yes. The formula for 3, 9, 27, 81 is 3^x, which means "3 raised to the power of x". The first term is 3, the second term is (3)(3), the third term is (3)(3)(3), the fourth term is (3)(3)(3)(3), etc. To get the answer for the 10th term you would have to multiply ten 3's.
Duane Habecker How will it help anyone to win the Lotto? Video is a joke.
the sequene is called geometric progression. Here the common ratio between any two successive terms is same. for ex, 9/3=3; 27/9=3 and 81/27=3, so to find the nth term the rule is a(r)powered by (n-1); here r= common ratio , n is the required term a is the first term of the sequence
if i have a recursive sequence 5,6,9,14,21,30,41,54,......
what is the function
4 + n
No it's wrong because first 5 in index 0 4+n first = 4 because 4+0
this was so easy and clear to understand. many thanks!!!
Great job! Really easy to follow. Thank you.
2019? Anyone??
Hi hi
You should stay in 2019 trust me
@@jackgilmore2793 so trueeee

How would you do this for more complex sequences like 1, 5, 21, 85, 341?

thank you sir

ugh i literally got so bored that i went to another vid and went to school and leanrend BITHING now here i am looking at this to cheat on my math HM 😒
I learned this by doing->
The Nth term's #= 1st Term + (Nth term -1 x "reason")
that would be An=A1+(n-1 x r).
(r) Reason would be the number you're adding to continue the sequence.
Ex as the one in the video: (7,10,13,16,19...). To find 100th term using An=A1+(n-1 x r)
A100=7+(100-1 x 3)
A100=7+ (99x3)
A100=7+ 297= 304
+Th3Haxor You method will also work. Well done!
I love your method of teaching, thank youuu
Why 4? Thank you soo much! As a 6th grader this is hard to understand!
I did that way quicker
Same sequence
Sequence 1; 7,10,13,16,19,....
/\
|
Is 3 times table +4
Sequence 2; 3,6,9,12,15,....
See sequence 2 is the same as S1 (sequence 1) just S2 is -4 less
So you do 3 x 100 = 300 + 4 (from the 3 being in the 3 x table S2) and the total is 304 :D
Caitlyn Targett 😎 cool 😂😂😂😂
Great one! One of the best video about this topic so far!
I wish my teacher wasn't so confusing and was CLEAR LIKE U!!!
Finally a video that does not treat me like a third grader!
I try.
why what is the problem with grade 3
Call it 3x+4
Wow you are good at teaching math! Wish you could teach more people like this way, to understand math!
