n 3 x n 2 n 13 n 1 x n2 5n n3 n 1 n 1 x n 5 3 n7

n = 3 x n + 2 / (n + 1)3 n = 1 x n2 - 5n / n3 + n + 1 n = 1 x n + 5 / 3 n7 + n2

Solution

Hi, you can use calculator TI 83 to solve summations so, 22) Converge when you do the summation you get, 0.3238428218, as you can see the numbers are getting smaller and smaller. 24) Diverge, because the ratio test is inconclusive. 26) Converge, because you get 9.42375 which means the series is getting smaller and smaller, and not going to infinity.
