First note that
![\frac{2^n+1}{2^{n+1}} = \frac{2^n}{2^{n+1}} + \frac{1}{2^{n+1}} = \frac{1}{2} + \frac{1}{2^{n+1}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%5En%2B1%7D%7B2%5E%7Bn%2B1%7D%7D%20%3D%20%20%5Cfrac%7B2%5En%7D%7B2%5E%7Bn%2B1%7D%7D%20%2B%20%5Cfrac%7B1%7D%7B2%5E%7Bn%2B1%7D%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2B%20%5Cfrac%7B1%7D%7B2%5E%7Bn%2B1%7D%7D)
If you take limit, then you have
