Math Worksheets

Videos, activities and worksheets that are suitable for A Level Maths to help students learn how to answer Geometric Series and Geometric Sequence questions.

Geometric Series / Sequence : Example (1)

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 = ab

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. 2 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.
