Shawn Beck · Answer 1

25, 125 3, 6, 9, 12 or 4, 8, 16 is the correct answer.

Step-by-step explanation:

Geometric progression is also known as geometric sequence and it is a sequence of numbers where each term after the initial one is found by multiplying it by a commom ratio, which is a fixed, non-zero number.

The first sequence has 3 as the common ratio. The second one has 5 and the last one, 2. Option 3 doesn not have one, so it is the correct answer.
