o 1. (20 points) Consider the series Emkpga. (a). Write out the first 5 terms of the series, i.e., a1, (12, a3, 0.4, 0.5. You do not have to simplify them. (b). Write out the first 5 partial sums of the series, i.e., 81, 82, 83, S4, S5. Do you see the pattern? (Hint: think about logarithm rules) (c). Using the pattern you noticed in (b), write a simple formula for Sn. (d). Use your answer in part (c) to determine if the series 22:1 (1,, converges or diverges. If the series converges, find its sum
