Homework Statement
I should know this (it's been a few years) but can't seem to get the answer for: Ʃ (from i = 0 to n) 0.5-i the answer is apparently 2n+1-1 / 2 - 1
how do I go about getting this?
Homework Equations
I tried Ʃn-1k=0ark = a* 1-rn / 1 - r
with no luck
The Attempt at a Solution
= a* 1-rn+1 / 1 - r (which is wrong)Thanks very much!
