n5n Use the ratio test to determine whether (n + 2)! converges or diverges. 7 2 (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n > 2, lim = lim n 100 an 72 +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 (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose v
