n(-9)n (1 point) Use the ratio test to determine whether converges or diverges. n! n=8 (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n 2 8, lim an+1 lim n-+co an n-+00 (b) Evaluate the limit in the previous part. Enter co as infinity and -co as -infinity. If the limit does not exist, enter DNE. lim an+1 n->co an (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose
