Question

Given the following geometric sequence, find the common ratio.33,99,297,891,2673,…Give your answer as a reduced fraction, if necessary.

Answer 1

SOLUTION:

From the given geometric sequence gives

The common ratio. reduce

$r=\frac{99}{33},r=\frac{297}{99},r=\frac{891}{297}$

Simplifying this gives

$r=3$

Therefore the common ratio is r=3
