Question

What is the common ratio for the geometric sequence below, written as a fraction?

768, 480, 300, 187.5, ...​

Answer 1

r =
`(5)/(8)`

Explanation:

The common ratio r is the ratio between consecutive terms in the sequence.

r =
`(480)/(768)` =
`(300)/(480)` =
`(187.5)/(300)` =
`(5)/(8)` = 0.625 ← as a decimal fraction
