a geometric sequence
The sequence have a common ratio of 4
Explanation:Sequence: 0.5, 2, 8, 32, 128
An arithmetic sequence is gotten using a common difference
common difference = next term - previous term
common difference = 2 - 0.5 = 1.5
common difference = 8 - 2 = 6
common difference is not the same. Hence, it is not arithmetic sequence
A geometric sequence is determined using a common ratio
common ratio = next term/previous term
common ratio = 2/0.5 = 4
common ratio = 8/2 = 4
common ratio is the same. Hence, it is a geometric sequence
The sequence have a common ratio of 4
