I don't even know how you teach this so fluently and easy to understand, but keep doing it for others! I can't BELIEVE this only has around 4000 views a video. I don't see one dislike though on most of the vids. :)
Oh thank God! My mom wants me to take the SAT after 12th grade and I was so scared it was going to be hard as hell. Now I see it's not hard at all. These are kind of fun actually. As long as I learn all the English mathematical terms I should be fine. Thank you so much for posting these videos!
Taking my SAT tomorrow, last time I took the test I got a 680 in Reading, a 690 in Writing and a 500 in Math. These videos are helping a bunch man, hopefully I do better tomorrow!
For 8:31 there is another way to solve the problem. Albeit it is more complicated, it can work for when the answer is not always as simple. So you start by creating a system of equations (Derived from the first two terms): (82/x) + y = 42 & (42/x) + y = 22. First, multiply both equations by x so you should get: 82 + xy = 42x & 42 + xy = 22x. Next, set both these equations equal to each other. I decided to negate one of the equations and got 40 = 20x. Therefore, x is equal to 2. I plugged it into one of the equations and solved for y, which is 1.
You are absolutely amaZing, thank you so much for the great effort you're putting into this. You're so incredibly advantageous. I hate math, however, I'm really enjoying your videos and having fun while solving these problems. Thank you :) Lots of Love from Tunisia
In all the american SAT math vids I watched about sequences, I never see arithmetic and geometric equation formulas being used. Is it common practice to translate like this? Does any one use Un=U1+(n-1)d ?
For the first problem my shortcut is just taking 127 and divide it by 6. That doesn't work, so I go down and I try to divide 126 by 6. I get 21, which translates to the word "rusted" being fully spelled 21 times. It's only common logic that the next letter after, the 127th, must be 'R'.
Divide the end result sequence # (127) by the # of letters in the word (rusted). use the remainder and count that many into the word rusted.....BING. ;) This can be used across the board.
for the first question i just divided 127 by 6 (the number of letters in rusted) and got 21.166 so i concluded that 21 has to be how many full times the word rusted fit into 127. then multiplied 21 and 6 to get 126 and so i knew the letter was going to be R
basically i learned them now i forgot plz send me a message saying how you work this out send it plz whats teh nth term for -3,0,5,12,21... plz sned me a message saying how to do it i subscribed

10 years later and this is still helpful, thank you!!!!
This channel is a life saver to study from
The number of viewers doesn't matter.. Keep it up and post as much as you can.
Your explanation is extraordinarily vivid.....

You've helped me increase my confidence for taking this test x 1000. Thank you so much!
Thank you! I'm preparing for the latin american version the SAT - the PAA, and you've been very helpful (:
You explain so well! This is really helpful. Please keep posting more video. Also, could you make a video with harder sequence problems? Thank you!
Thank you and God bless your soul

Thank you much for the help. this truly nice God bless u
really helpful !! cudnt a little but faster way be to divide 127 by 6 and the remainder wud be the letter ? in this case the remainder is 1 which is r
OMG THANK YOU SO MUCH! IM TAKING MY TEST TOMORROW AND THIS HELPED ME SOO MUCH!
Fastest way in calculator: 127/6 = 21.166. 6(how many repeat)*21(whole number of previous calc.) = 126. 127-126 =1=R
You probably raised my score 200 points last time.... Here's to another 200 if I am lucky!
Something I just picked up that is absolutely amazing is (A1 * A3)^1/2 = A2 so the square root of 82 * 22 = 42(rounded)
Thank you so so so so so so so much!
Does it work for every problem?
Wait but on the 1st one 5 is also a multiple of 120 so is it the number at the end?
Exactly! I learned how to do these kind of problems when I was on my 6th grade. And I used the same method for these problems. ;) Try it
good work! wish my teachers were like you
please add more videos . exam questions .thanks

JDrArtLife i do, but i am in the french school system have never seen that method in american sat study books
Love this video. Please make more
If you're in the US and applying to schools for the fall semester of 2014 I suggest you take it in October, not after you graduate.
u r so good
i try other perps on youtube but i understand you more get it up
wish u could tutor me
You're AWESOME!

easy to understand. thank you so much
Greater than. Not greater than or equal to? Did I miss something?
ur just amazing. keep up ur videos please
hey titan! thanks gl on your test!
Thanks.am loving maths again
my nigga
This guy is good.
If you want to the last part algebraically:
You can say: 82/x + y = 42 and 42/x + y = 22
Now is the good time to use systems of equations.
Divide the end result sequence # (127) by the # of letters in the word (rusted). use the remainder and count that many into the word rusted.....BING. ;)
This can be used across the board.
Dude, ur awesome. Thank u sooooo much
thank you so much.
thank you!
This is really funny for any highschool student in India.
Thank you! :)
AMAZING
for the first question i just divided 127 by 6 (the number of letters in rusted) and got 21.166 so i concluded that 21 has to be how many full times the word rusted fit into 127. then multiplied 21 and 6 to get 126 and so i knew the letter was going to be R
lol just seemed a whole lot easier and quicker to do it that way though i don't know if this applies to every sequence question of course
i love you
Exactly my thoughts right now
always use the last number
this is my exact situation
there is even a much, much easier way, to calculate what the 127th letter will be :)
I subscribed to you :)!!
better than kd!!
Grazie
Gracias
Merci
Ty
u kind of sound like bob saget and khan mix
basically i learned them now i forgot plz send me a message saying how you work this out send it plz whats teh nth term for
-3,0,5,12,21... plz sned me a message saying how to do it i subscribed
Thumbs up if you took the sat today
