Step-by-step explanation:

a geometric progression is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio

1, 5, 25, 125, ...

yes, the common ratio is 5

3, 6, 9, 12, ...

no

3, 6, 12, 24, ...

yes, the common ratio is 2

3, 9, 81, 6, 561, ...

no

10, 20, 40, 60, ...

no
