Answer
The given sequence is a geometric sequence because the ratio of any two consecutive terms is constant.
The common ratio = 2
Work Step by Step
The given sequence is = 4, 8, 16, 32,64.
This is a geometric sequence because the ratio of any two consecutive terms is constant.
The common ratio = $\frac{64}{32}$ = $\frac{32}{16}$ = $\frac{16}{8}$ = $\frac{8}{4}$ = 2
