A list of numbers that follows a rule is called a sequence. Sequences whose rule is the multiplication of a constant are called geometric sequences, similar to arithmetic sequences that follow a rule of addition. Homework problems on geometric sequences often ask us to find the nth term of a sequence using a formula. Geometric sequences are important to understanding geometric series.

This video introduces geometric sequences.
Geometric Sequences (Introduction)

A Quick Intro to Geometric Sequences.

This video gives the definition of a geometric sequence and go through 4 examples, determining if each qualifies as a geometric sequence or not.
### Geometric Sequences - Find the nth term

Geometric Sequences: A Formula for the' n - th ' Term.

This video derives the formula to find the 'n-th' term of a geometric sequence by considering an example. The formula to find another term of the sequence.

In this video we look at 2 ways to find the general term or nth term of a geometric sequence.
### Geometric Series

We can use what we know of geometric sequences to understand geometric series. A geometric series is a series or summation that sums the terms of a geometric sequence. There are methods and formulas we can use to find the value of a geometric series. It can be helpful for understanding geometric series to understand arithmetic series, and both concepts will be used in upper-level Calculus topics.
