Best ResponseYou've already chosen the best response.3In a geometric series, the series will converge if \[\large r<1\]In this case, \[\frac{1}{2} <1 \implies \frac{1}{2}< 1\] therefore the \[\large \sum_{n1}^{\infty}4(\frac{1}{2})^{n1} = C\]

Best ResponseYou've already chosen the best response.3Because it converges, your sum : \[\large S=\frac{a}{1r}\] where \[\large r=\frac{1}{2}\]
