[DTube] Geometric Series: Deriving the Summation Formulas

BY: @masterwu | CREATED: Jan. 14, 2019, 10:30 p.m. | VOTES: 323 | PAYOUT: $2.81 | [ VOTE ]

I'm in the process of uploading all of my Youtube videos to DTube, where they can be recorded on the Steem blockchain

In this video, we derive the formulas for summing a geometric series, firstly to the nth term and then to infinity.

The formulas are:

  1. Sn = a(rn - 1) / r - 1

  2. S∞ = a / r - 1

We also discuss the concept of convergence and divergence for the geometric series.

Sequences & Series

What are Geometric Sequences?

Modelling Price Inflation with Geometric Sequences

Geometric Sequences: Find the 4th term given the 7th term

Geometric Sequences: Find the first term and common ratio

Geometric Sequences: The Geometric Mean

Geometric Series: Deriving the Summation Formulas

Thanks for watching. Please give me a "thumbs up" if you have found this video helpful.

Please ask me a maths question by commenting below and I will try to help you in future videos.
