Week 2- Geometric Series

This week, we started by learning how to find a common ratio for geometric series’. Geometric series are when one number is multiplied by the same number each time.

Ex. 3, 9, 27

To find the common ratio (r.) We have to divide the first term by the second term. \frac{9}{3} = 3

`This means that the common ratio is now 3. When we multiply each term by 3, the geometric series continues correctly.
