Hi: The series is alternating of the form(a_n)*(-1)^n, where a_n = e^n/n^3. Because limit (n->inf)[a_n] not= 0 (a_n->inf as n->inf}, the series diverges. Regards, Rich B.
Hi: You are correct. The test criteria are, 1) The terms a_n are of decreasing sequence; clearly 1/(3n+1) is decreasing on [1, inf]. 2) Limit(n->inf)[a_n] = 0. Both criteria having been met, we conclude convergence. Regards, Rich B.
