B.
The given sequence is not geometric.
A. The given sequence is geometric. The common ratio is 5.
To find the common ratio, we can divide each term in the sequence by the term before it:
5/1 = 5
25/5 = 5
125/25 = 5
Since all the ratios are equal to 5, the sequence is geometric with a common ratio of 5.
