Q: Is the series 1/2n convergent or divergent? If convergent find it's sum.(adsbygoogle = window.adsbygoogle || []).push({});

I see that the limit as n goes to infinity is zero but that does not prove C or D. It seems like it would be divergent but why? How can that be shown?

Any direction/help would be greatly appreciated.
