# Math Help - induktion

1. ## induktion

Show that "Attchment"

for every positive Z

2. I would feel better about this if you would show some effort yourself! In any induction problem, the "base case" is usual fairly simple.

To show the "induction" step just note that the n+1 sum is just the n sum plus $\frac{n+1}{2^{n+1}}$.

3. thats all the information I got on this problem, but I found the answer to it in my notebook, ill write it down and ill show you what kind of answer I wanted!
