Use the ratio test to determine whether n9n n=2 (n+2)! converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n 2, lim An+1 an lim (b) Evaluate the limit in the previous part. Enter as infinity and -o as -infinity. If the limit does not exist, enter DNE. An+1 an lim nx (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose
