The formula to calculate the common ratio (cr) is:
\[ cr = \frac{a(n+1)}{a(n)} \]
Where:
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.
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.
