Question

Find the common ratio for this geometric sequence. 0.25, 1.25, 6.25, 31.25, ...

Answer 1

Given data:

The given geometric series is 0.25, 1.25, 6.25, 31.25, ...​

The expression for the common ratio is,

`\begin{gathered} r=(1.25)/(0.25) \\ =5 \end{gathered}`

Thus, the common ratio is 5, so first option is correct.
