- The most requested video for a long while! How to understand sequence questions on the GRE and GMAT. Sequences (sometimes called arithmetic sequences) come up occasionally on both these tests and if you are aiming for a 170 or 700 then it is definitely worth knowing!
I offer private GRE / GMAT tutoring online at a fixed rate of $140/hr. Please get in touch via the email below, or through my tutoring website: www.gretutorlo...
Enquiries: philip@gretutorlondon.com
The GRE and GMAT are two of most used graduate exams for those seeking to study a Masters Degree or Masters in Business Administration (MBA) degree. The Graduate Record Exam and Graduate Management Admissions Test have been taken for over 50 years and are taken by approximately 600,000 and 300,000 people worldwide annually, respectively. These exams are typically taken between the ages of 18-40, by those who have completed, or are about to complete, their Bachelors Degree.
Enquiries: philip@gretutorlondon.com If you’re now ready to get into your dream MBA program, my former student, Angel, is offering virtual private Admissions coaching. She was admitted into Harvard Business School, The Wharton School of Business, and Columbia Business School (accepted into every school she interviewed for) after graduating from UCLA with a degree in Communication. She also got 3 perfect scores on the GRE’s Analytical Writing Assessment (99th percentile).
Here is her link - linktr.ee/ange... - and you can reach her at angellinzhu@gmail.com with the subject line, “PHILIP SENT ME.”
The only hard thing with Philip is finding an original way to compliment or thank him! Extraordinary work!
Haha true
I feel so lucky to have come across this TH-cam channel. Much more lucky that I'll now enjoy more videos that have been done because of people's requests. I'm totally grateful 💕
Philip, you're a great tutor in quintessence. Your materials have been completely easy in comprehension May God wax you stronger in knowledge.
"Philip" translates as the !!! best tutor ever !!!
Thanks philip clearly better than watching a 1 hour video in terms of the concepts I could cover in the same period
i'm so glad i found you.. thank you for the wonderful content
I'm glad you found the channel too Pranava!
Very very nice technique!! this is exactly the type of training that, cumulatively, can help people speed up and score higher!! I'll let you know how much I improve! Btw, if you don't have a Paypal link for donations, I highly suggest you make one, because even though not everyone may be able to pay for full tutoring, many who have benefitted from your videos will want to contribute as they can for the great tutoring you offer freely
Hey Edward, thank you. No PayPal unfortunately but I do have a patreon link in the description.
Your channel has been such a blessing. What a pity i found it after i banged my first GRE. I'm re-writing on Dec 18 and i'm hopeful to score at least a 320 this time. Thank youuuuuuuuuuuuu!
Genius is back after short break!
Thanks Arif!
I've honestly never done sequences before and I don't know how I've gotten away with it for so long without doing them. However, you've explained it in such a simple way that I was able to solve the last two problems on my own without any issues. Thank you! (my GRE is tomorrow early in the morning. Wish me luck!)
Good luck tbf!
Your explanation is mind blowing. Thanks Philip
YOU ARE THE GREATEST TEACHER EVER.
You're the best math teacher!
I'm glad I found you Philip... Thank you so much for the extraordinary work
Philip,you're the best. I got stuck with sequence just the previous day.and you made it easy today.Thankful to Allah that i found you.Thanks ♥
Glad it helped!
Excellent technique Philip, I'm totally grateful 💕
Soooo helpful! Studying for the GMAT and you made this understandable 🙏🏽🙏🏽
Glad it was helpful BC!
I think of skipping a chapter, thinking I wnt be able to do it... n then I see ur video... Boom... one video n I understand the concept n how well🙏🏼🙏🏼
Yaay! :)
@@TheTestedTutor can u plz do one complete video covering everything bout everything we need to know to crack word problems
Yayyyyyy! I can't believe I got that final question right! Thanks Philip, you make this so easy
My word, this is excellent
love this!!! i was always scared to try out Qs on sequences but now im way more confident! The translation bit really helps, thank you!!!!
Really Helpful. Love from Bangladesh 🇧🇩
Glad it was helpful!
Thank you Philip! This makes it so much easier to understand. Could you please make a video on arithmetic progressions?
Check out my vid on sequences!
This was so incredibly helpful! I was doing it all wrong before seeing this! Thank you!
I'm so happy I found you ☺️
Thank you Philip.
Thanks Phillip for Gr8 and detailed explanation.
Always respond to requests!
Thankyou so much Philip.
Was waiting for this video
:)
All the GRE and GMAT tutors are out of their jobs in Ghana. In Ghana we say Philip God Bless You.
Wow, thank you Alimi-Yao
Am also watching from Ghana. Philip, you are the best !!
Thank you, Philip. Your videos have been helpful.
You are very welcome
Your video helped me a lot. I like the way you explain things part by part. Could you please make a video on venn diagram?
Yes, soon Khandaker!
I love your really sublime methods of teaching. GRE is in trouble this time. 😂
Thank you so much. I was finding sequence difficult before now😩
Thank you, Philip!
Thank you for tour detailed explanations.🌹Could you please make a video about the writing section of GRE
I did one on the essays you can check out...
Hi Philip! if we put K1=+2 or -2, we will get K4=64... Both the solutions are possible
Thank you! I was lost in this before.
You are welcome!
Hey Philip, really like your videos! It helped me a lot in my preparation so far. One request can you make a video on parabola'a and set theory. It will be very helpful. Thank you...
That's a tough one! I'll try!
@@TheTestedTutor please do it. I am having trouble understanding them compactly for gre
Thank you so much for making it so simple.
Thanks priyanka:)
Great videos to understand the concepts, could you do one on Venn diagrams always struggled with those
Did you see my recent vid on this?
Great explanation
Philip, all your videos are great, i love them.
Can you please explain, in the last problem, if n>1, then how can a4 be a negative term?
N is positive but not necessarily a4, which is just one term. N is the term, such as 1st term 4th term. The term itself can be negative
@@TheTestedTutor then why did we not consider -8 in the second problem?
@@ayushphukan2448 Seems like we can consider -8 in the second problem, since they have not mentioned anything about the term itself, and just that n>1, so k1 would be +2 or -2
Thanks but I believe there is an error in your video. In the second example with trying to find the value of k subscript 1, the final answer can be +2 or -2. The expression n>1 only applies to the subscript of k. Nothing says k cannot be negative. You would need a k>1 to make -2 a wrong answer. In the 3rd question, even though you have n>1, you get a negative answer.
Hey can you make a video on Mixture and solutions problem in GRE?
Thanks a lot, it really helped me. 👌🏻👍🏻
Thanks Philip!
How can a4=-51? Doesn't the restriction "..for all n>1" mean that a4 should be a positive number?
Hi, the n>1 means that the subscript "n" is not a negative number. It does not infer anything about the final outcome.
@@pascalokoye5727 Hi. Could you please explain what the subscript means in this context? I assume it means the position of the term which I do not expect to be negative in any scenario. Phillip had brought it to our attention earlier (n > 1 being positive). So, I’d like to understand why 51 wasn’t the answer. I see a typical GRE question having -51 and 51 in the options and it could be really confusing.
@@stephanieamatesiro7263 me too. I need clarification on this particular answer
@@bonjourciao2525 Pascal is totally right. N is the anem of the term. A4 etc is the term itself, which can be negative
it says n is positive, where n is the number of terms...but why can't the value of n be negative?
Many thanks for the valuable content!
My pleasure!
I love your channel!
Ty Kirsten!
Very useful
god bless you for your channel
translate the math into words! Whattay idea sir jee!
Can you do a video on Arithmetic Progressions for GRE perspective? All three levels Easy-Medium-Hard.
Eg. Sum of all number between 99-302 that are divisible by 4
Than you so much
you're amazing!!! Thank you.
Thank you, very helpful!!
You're welcome!
Second question:
The condition should be n is bigger than or equal since the relation is k_(n+1) = (k_n)^2-1
Amazing!
can you recommend a site online to do practice more problems??
really easy to understand
Thanks Chenali
AMAZING!
Superb
If n>1, then the a4 would be positive, isn't it 51 ?
n here is the position of the term in the sequence. n>1 says that the postion of the term will always be positive(>1) and not the term itself. That is, sequence is only valid for all the terms with position greater than 1
I liked this one
Hey Phillip, what is your opinion on Magoosh?
Good resource, I even did some questions for them
GODSEND
so the 1 st term is not really the 1 st term its already considered the 2nd or next term ..
Very complicated
i dont understand this
