Determine if the sequence is geometric. If it is, find the term named in the problem.

25.) 4, 8, 16, 32, ...

Find a9 (9 is a lowered power to a)

120

Step-by-step explanation:

Each new term is twice the previous term, so this is a geometric sequence. The applicable formula is

a (n) = a (1) * 4 * (n - 1)

and so a (9) = 4*4 (9 - 1) = 120
