1) -1, -2, -4, -8 ...


2) 2, 4, 8, 16 ...

Answer 1

1) -16, -36, -64

2) 36, 64, 128

Explanation:

1) -16, -36, -64

2) 36, 64, 128

For the first one, -2^0=1, -2^1 = -2, -2^2 = -4 and so on.

For the second one, 2^1 = 2, 2^2 = 4, 2^3 = 8 and so on.

So the only thing that is change is the power or (^x).
