I'm pretty sure the answer is Finite geometric sequence because it has an end point.

Answer: Second option is correct.

Explanation:

Since we have given that

6,12,24,48,.......1536.

Here, a = first term = 6

r = common ratio =
(a_2)/(a_1)=(12)/(6)=(24)/(12)=(48)/(24)=2

And it has last term i.e.
a_n=1536

So, it becomes finite geometric sequence as it has common ratio and last term is defined due to which it becomes finite.

Hence, Second option is correct.
