Consider the series sigma_n=1^inifinty a_n where a_n = (n+3)!/e^n+9 squareroot n

Question

Consider the series sigma_n=1^inifinty a_n where a_n = (n+3)!/e^n+9 squareroot n + 1 In this problem you must attempt to use the Ratio Test to decide whether the series converges. Compute L = lim_n rightarrow inifinity |a_n+1/a_n| Enter the numerical value of the limit L if it converges, INF if it diverges to infinity, MINF if it diverges to negative infinity, or DIV if it diverges but not to infinity or negative infinity. L = Which of the following statements is true? The Ratio Test says that the series converges absolutely. The Ratio Test says that the series diverges. The Ratio Test says that the series converges conditionally. The Ratio Test is inconclusive, but the series converges absolutely by another test or tests. The Ratio Test is inconclusive, but the series diverges by another test or tests. The Ratio Test is inconclusive, but the series converges conditionally by another test or tests. Enter the letter for your choice here:

Explanation / Answer

Here by root test we get   infinity

so if   limit we got infinity

L >1 it means   diverges

B
