Question

Use the ratio test to determine whether ?_{n=5}^{?} frac{7^n}{(7n)^2} converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n ? 5, lim_{n??} |frac{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??} |frac{a_{n+1}}{a_n}| = (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose Converges Diverges Inconclusive Note: You can earn 40% partial credit for 2 - 3 correct answers.
