Summation of a?n from n=1 to infinity=1-1/10+1/100-1/1000.......

For the following alternating series,

Σ an = 1-1/10+1/100-1/1000+1/10000 .......

^(from n=1 to infinity)

how many terms do you have to go for your approximation (your partial sum) to be within 1e-08 from the convergent value of that series?
