Question

Use the ratio test to determine whether ?_{n=14}^{?} (n(-2)^n) / n! converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n ? 14, lim_{n??} |a_{n+1} / a_n| = lim_{n??} (b) Evaluate the limit in the previous part. Enter ? as infinity and -? as -infinity. If the limit does not exist, enter DNE. lim_{n??} |a_{n+1} / a_n| = (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose

(a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n ? 14,
lim_{n??} |a_{n+1} / a_n| = lim_{n??} 
(b) Evaluate the limit in the previous part. Enter ? as infinity and -? as -infinity. If the limit does not exist, enter DNE.

(c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose

$Use the ratio test to determine whether ?n=14^? (n(-2)^n) / n! converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n ? 14, limn?? |an+1 / an| = limn?? (b) Evaluate the limit in the previous part. Enter ? as infinity and -? as -infinity. If the limit does not exist, enter DNE. limn?? |an+1 / an| = (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose$
