[tex]\Sigma^{\infty}_{n=0}[/tex][tex]\frac{1}{2^{n}+(\frac{1}{3})^{n}}[/tex]
Homework Equations
The Attempt at a Solution
I decided to use the ratio test:
[tex]\frac{1}{2^{n+1}+(\frac{1}{3})^{n+1}}[/tex] x [tex]\frac{2^{n}+(\frac{1}{3})^{n}}{1}[/tex]
And I got [tex]lim_{n\rightarrow\infty}[/tex][tex]\frac{1}{2 + \frac{1}{3}}[/tex]
But I'm A) pretty sure it's wrong and B) if not, what do I do after that step?
