Answer 1

@kropot72
Would you mind helping me with one more? I did this one, but i think i did it wrong.. What formula do i use?

Answer 2

The n^th term is found from the following formula:
\[n ^{th}\ term=ar ^{n-1}\]
where a is the first term (32 in this case) and r is the common ratio.
\[r=\frac{16}{32}=?\]

Answer 3

I don't think i'm doing this one right.. I keep getting 0.5 as the answer?

Answer 4

The answer is 0.5. You are correct :)

Answer 5

ohh, okay. i wasn't sure if i'm supposed to mulitply (32)(.5) first or do the exponents.

Answer 6

In the order of operations, exponents come before multiplication.

Right, that's how i did it.
Thank you so much for helping(:
