Question

What is $r$ in geometric progression?

Answer 1

In geometric progression, $r$ is the common ratio of the two consecutive terms.

The ratio of the term and its preceding term remains constant.

Example: $5,25,125,625,....$ is a geometric progression.

The common ratio $r$ of the geometric progression is,

$r=\frac{25}{5}=\frac{125}{25}$

$\Rightarrow$ $r=5$
