Since the problem asks

**two**questions, and you have only one answer, it is obvious that your answer is NOT correct.

And, in case you think I am being picky, what you give not the correct answer to**either**question. Perhaps if you showed how you got that we could point out errors. - September 27th 2011, 08:46 PMl flipboi lRe: Finding an. Verify my answer.
I just needed help with finding the solution for the first part. Which is find a(subscript)n.

Here's what I got so far... I realize I did the first part wrong, here's where i'm stuck tho:

(6-n/4^n) - (6-(n+1)/4^(n+1))

(6(4^n)-n/4^n) - (6(4^(n-1)) - n + 1)/4^(n-1)

....

Where do I go from here? - September 29th 2011, 01:22 PMTedRe: Finding an. Verify my answer.

All what you need is your algebra.

Try to write your equations using Latex. That's will make our life easier. - September 29th 2011, 02:11 PMHallsofIvyRe: Finding an. Verify my answer.
