To test the series for convergence, you can use the P-test. K = VK2 (You could also use the Integral Test, as is the case with all series of this type. ) According to the P-test: O diverges k =1 VK2 O converges k = V K2 O the P-test does not apply to E k = VK2 Now compute s3, the partial sum consisting of the first 3 terms of 1 K = K2 S3
