Good video! It can be hard to remember which technique to use on different series; noticing the structure is key. Do you ever plan to make videos on Number Theory, Discrete Mathematics, Abstract Algebra, etc? I would love to see discrete topics covered, such as combinatorics, graph theory, information theory, and so on.
The first and last terms don't cancel with any other terms because there is no term before the first or no term after the last. The rest all terms cancel each other out.
Lol, they have a speed increase button now. And I'm sure that 3 years ago you could have found or written your own browser plugin to accomplish the same thing. That's the obvious solution instead of complaining about the gift of a video presentation given by the near-genius that is Sal Khan.
THANK YOU SOOOO MUCH!!!!! This was incredibly helpful!! I love how you don't skip steps in order to speed through everything. Great video!!!
Chat with me on Instagram (chouaibzaghoud)
Awesome explanation. Thank you very much. Keep up the good work!!!!
Did anyone hear at th-cam.com/video/qUNGPqCPzMg/w-d-xo.html he said “Or I will run out of real estate" ?????
Thank god i found this video!!! Thank youuu for the interesting way of teaching :)
thank you!!!!!!!!!!!!!!!!!!!!!!!!! yaaayy

Thanks Sal Khan for such a clear and concise video.
Always a Blessing in disguise.
🤩
“similar-larly”😭😂 love this dude❤️
Thank u so much sir ❤🎉
So what if it happens where two of the same term don't cancel at the end of the telescoping series? Does it count as that term squared?
THANK YOU HAVE A PCAL QUIZ TMRW MY TEACHER HASN'T BEEN HERE FOR A WEEK
so when you find the limit of the sum, is it just divergence test?
Explanation on point 👍
its funny how the video seems to get over faster even tho u slow it to 0.5x because its jus too funny XDXD
I missed the first day of series in my clac class so this was very helpful for catching up
great video!
Is there a way to find the sum without using partial fractions?
Really helped. Thank you!
So helpful! Thank you
Every time i came to his videos I learned something new. Thank you sal!
How do you know what terms cancel out when you plug in N??? I don't understand this at all.
The first and last terms don't cancel with any other terms because there is no term before the first or no term after the last. The rest all terms cancel each other out.
awesome explanation
Sal Kahn is a great teacher.
Thanks a lot!
what if it's not n+1 but n+3 in the second term?
Thanks^_^
This will probably be a really popular video because it's hard to explain in class...
Op master ji
fascinating stuff....
Over my head haahaa im ouyya here
u could have made the calculatons/derivation faster as its 6-7 grade math.. but still really great video
Use hindi for better understandkng
What a stupid comment
Nice video. But it would have been better if you had gone a bit faster... It's pretty elementary stuff.
