Geometric sequence and Series : ExamSolutions

Geometric sequence and Series.
In this video, I'll show you how to find the nth term for a geometric sequence and calculate the sum of the first n terms of a geometric sequence. I'll define a geometric series and its formula.

Don't know about the school bit but good to hear that you feel you are making progress

Are the videos from 2011 *REALLY* helping?

[alaazka]

This channel deserves more recognition I swear to god.

[thhb]

man you changing lives out here bro I can ace tests while being lazy at the same time like never before.

[maleceb]

Honestly, no other channel has been as helpful as this one, thank you so much!

Is anyone else watching in quarantine/lockdown? This video was really helpful. Thanks.

If i get an A in maths its entirely because of you

[jean-paulbrummer]

3 hours of lessons at school and still didn't get it < watching a 9 minute video and understanding it. THANK YOU!

I suck at Maths! My tutor taught me this today and nothing went to my head but this tutorial really made me understand geometric progression to some extent!! Thank you so much!!
:) :)

I Never Commented On any video But This Was Great Liked Commented and Subscribed.

Absolutely top notch lesson. Thank you so much. I've been training myself to become a programmer for a while now but I also love mathematics, so I find myself often making programs involving mathematics. Using math, you can find O(1) constant time algorithm solutions, which is the fastest kind of algorithms you can possibly have.

Go on my website and look in the index for geometric progression, sum to infinity. It is there.

Fantastic video, as a mature student self teaching my A levels this is a fantastic resource.

I noticed a small mistake at the end of this video,
when you work out the sum of the first 10 terms you have divided by "3-1" instead of "4-1"

You are saving my life right now so much better than my actual teacher

[DrSickShots]

A levels coming up. Thanks to you, i can progress alot faster without having to go to school! Thanks

[wizzi]

better than my teacher. (i meant i learnt more from you'r explanation then my teacher's)

[ronaldnabutola]

The best tutorials of all time.Excellent sir.

[ExamSolutions_Maths]

Sorry to say, but there is no mistake. It is r-1 which is 3-1 as the common ratio is 3. I think you are doing a-1 rather than r-1.

This has really helped with my 11 Maths C Assignment. Thank-you

Can u do this step by step: The first fifth seventh terms of an AP correspond to the first consecutive terms of a decreasing GP. The first term of each progression is 64, the common difference of the AP is "d" and the common ratio of the GP is "r". a) I) write 2 equations involving "d" and "r" ii) find the values of "d" and "r"
