How can I know what a summation of series will eventually converge to? For example, in this series:
\[\sum _{ i=1 }^{ n }{ { 2 }^{ i1 } } \]
What are the steps I should take to know that it will eventually converge into what equation?

Thanks for the hints. By the way, it does converge. It converges to \[2^n1\]

But of course, if the series goes to infinity, then it wouldn't converge.
