1. The problem statement, all variables and given/known data:(adsbygoogle = window.adsbygoogle || []).push({});

The following is a geometric series.

Determine whether series is converges or not.

For the series which converge, enter the sum of the series

[tex]\sum^{\infty}_{n=1}\frac{7^n+3^n}{8^n}[/tex]

2. The attempt at a solution:

I've looked into calculating [tex]{r}=\frac{a_{n+1}}{a_{n}}[/tex] but the series isn't constant and neither is r : [tex]\frac{10}{8}{+}\frac{58}{64}{+}\frac{185}{256}{+...}[/tex]

I feel like there is another approach to solving this problem that I am missing. Your help is appreciated, thanks.
