Answer:

Common ratio = 0.2 or 1/5

Explanation:

To find the common ratio of a geometric sequence, we divide two consecutive terms. A succeeding term must be divided by a preceding term.

Thus, we can find the common ratio by dividing 125 by 625:

Common ratio = 125 / 625

Common ratio = 1/5 or 0.2
