    Finding Sum of Alternating Series to Desired Accuracy

    How many terms of the series do we need to add in order to find the sum to the indicated accuracy? The alternating series from n=1 to infinity of ((-1)^(n+1))/(n^2) |error| less than 0.0399 i got it down to 1/n^2 is less than 0.0399 but i can't figure out if n = 5 or n=6... please help:(
