Answer:

It's C.

Step-by-step explanation:

A geometric sequence has a common ratio (r) where each term after the first is obtained by multiplying the previous one by r.

Checking through the list we see it is C because:

Second term 15 = first term * 5 = 3(5) = 15.

Third term = 15*5 = 75,

4th term = 75*5 = 375 and so on.

The common ratio is 5.
