Question

HELPPPPP PLEASE !!!!!

Answer 1

0,5,10,15 is not the sequence of geometric.

Generally, to check whether a given sequence is geometric, one simply checks whether successive entries in the sequence all have the same ratio. The common ratio of a geometric series may be negative, resulting in an alternating sequence.

Explanation:

This is totally correct!

Answer 2

4th option 0,5,10,15

Explanation:

Let's check if the first choice is geometric.

2*3 = 6. is 6*3 = 18, yes! is 18*3 = 54. Yep! its geometric

the second option multiplies by -2, it is geometric

the third option multiplies by 1/5, it is geometric

The fourth option does not multiply by anything common, it is Not geometric
