What is the Common Ratio?

The common ratio is a measure used in geometric sequences to describe the ratio between consecutive terms. It is calculated by dividing a term in the sequence by the previous term. This ratio remains constant for a given geometric sequence.

Example Calculation

Let's assume the following values:

Step 1: Calculate the common ratio (cr):

\[ cr = \frac{15}{5} = 3 \]

Therefore, the common ratio (cr) is 3.
