Question 208033: Find the sum of each of the following infinite series. If a series does not have a sum write "no sum" as the answer.
1/2+1+2+4
I know that to solve thisyou just put S=A/1-R (A= first term, R= ratio) yet I dont get how I should do it with the fraction 1/2 (I know it sounds stupid but I dont get how to solve it when it starts with a fraction =/)

S=A%2F%281-R%29+

Here A=1/2 and R=2.
S=%281%2F2%29%2F%281-2%29
S=%281%2F2%29%2F%28-1%29
S=%281%2F2%29%2A%281%2F%28-1%29%29
S=-1%2F2

R^2
