(4 points) Use the ratio test to determine whether n6 converges or diverges. n=17 (n + 2)! (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n 17, an+1 lim = lim 818 an FX (b) Evaluate the limit in the previous part. Enter co as infinity and -oo as -infinity. If the limit does not exist, enter DNE an+1 lim = 818 an (c) By the ratio test, does the series converge, diverge, or is the test inconclusive?
