...Infinite series


An infinite series is an expression like this:

S = 1 + 1/2 + 1/4 + 1/8 + ...
The dots mean that infinitely many terms follow. We obviously can't add up an infinite number of terms, but we can add up the first n terms, like this:
S1 = 1
S2 = 1 + 1/2 = 3/2
S3 = 1 + 1/2 + 1/4 = 7/4
S4 = 1 + 1/2 + 1/4 + 1/8 = 15/8
