Geometric Sequences are sometimes called Geometric Progressions (G.P.’s) To sum these: a + ar + ar2 + ... + ar(n-1) (Each term is ark, where k starts at 0 and goes up to n-1)

This unit explores geometric series, which involve multiplying by a common ratio, as well as arithmetic series, which add a common difference each time. We'll get to know summation …

Learn how money grows in a bank account with geometric series! Discover how each deposit grows by a fixed percentage every year, creating a pattern. This pattern forms a geometric …

Sal introduces geometric sequences and gives a few examples. Notation used in this video is relatively advanced. Created by Sal Khan.

Practice your understanding of the geometric series formula.

In this video I want to introduce you to the idea of a geometric sequence. And I have a ton of more advanced videos on the topic, but it's really a good place to start, just to understand what …

A geometric series is the sum of the first few terms of a geometric sequence. For example, 1, 2, 4, 8,... is a geometric sequence, and 1+2+4+8+... is a geometric series.
