Thread: Rearranging Equation to determine conv/div

I just found it simpler to take a screenshot. I have no idea how to go about rearranging the equation like the solution does below.

Thanks.

Note that,

Thus,

Ahh, so there is a property that allows 3^(n+1)=3^n + 3^1

Am I right on that?

.

In general, where are positive integers.

You supposed to have known this in algebra. Not when learning Calculus.

Sorry I put + and thought *.

And it does so happen that people tend to forget things when they haven't done it in a while....hmm what an odd theory .

Thanks!
