**Geometric Series / Sequence : Example (1) **
**Geometric Series / Sequence : Example (2)**

**Geometric Sequences and Series (1 of 2)**

This video explains the difference between arithmetic (common difference -- addition, d) and geometric (common ratio -- multiplication, r) sequences.

Then it shows the relation between geometric sequences and exponential functions (y = abx).

It develops the nth term equation for geometric sequences by showing how the repeated multiplication involved is really just an exponent.
**Geometric Sequences and Series (2 of 2)**

Problems covered:

Find the nth term equation for the geometric sequence or find a specific term given:

1. The first few terms

2. A term and the common ratio

3. Two different terms

The formula for the sum of a geometric series is developed and then used to find the sum of a geometric series, given a series of numbers of summation (sigma) notation.
