Answer 5

First part:
A geometric sequence will have a common ratio between each of its terms so from the looks of it, all are geometric sequences.

Answer 6

Second part:
If you see carefully, as you go on to the next term you have to multiply each previous term with
1/2 in option A and D
AND
2 in option B and C.

Getting me till here? :)
