Question

Which spreadsheet would be used to compute the first seven terms of the geometric sequence an(32•(1/8)^n-1

Answer 1

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.

Answer 2

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.
