How do I interpret $\displaystyle \frac{1}{2^{(n-1)}+1}+\frac{1}{2^{(n-1)}+2}+\frac{1}{2^{(n-1)}+3}+...+\frac{1}{2^n}$
No it was to verify the inequality with that series > or = to 1/2.
How do I copy an equation from a previous thread and edit it in a new thread? Anyway , I have problem with sequences or series when the last term differs from the first. I don't know they look. For example in the above how does n=3 look compared to n=5? How do you incorporate the last term.
