are there certain formulae to find out where a certain infinite series converges, if it does converge(adsbygoogle = window.adsbygoogle || []).push({});

for example

[tex] \sum_{n=1}^\infty (\frac{3}{5})^n [/tex] certainly converges because it is between the infinite series

[tex] \sum (1+ \frac{1}{n})^n [/tex] and the series [tex] \sum (\frac{1}{5})^n [/tex] wich both converge Since both of them converge then sum(3/5)^n must converge.

But my question is WHERE does (3/5)^n converge??
