Answer:

The second table is correct.

Explanation:

Given: an = 32.
((1)/(8) )^(n-1)

1st term = 32*(1/8)^(1-1) = 32*(1/8)^0 = 32*1 = 32

Similarly, we can find the other terms.

By look at the table, the second one is correct.

In the first one, we have 32^(1/8) which is not correct.

Hope this will helpful.

Thank you.

Short Answer The second one (lowest one).
The first one multiplies the power by 32 which is not what you want. You want to raise the base (1/8) to a power. It get's dramatically smaller. In fact it might give you an underflow.
