For each of the following series, indicate whether the integral test
can be used to determine its convergence or not, and if not, why.

**A.**

Can the integral test be used to test convergence?
** A. ** no, because the terms in the series do not decrease in magnitude** B. ** no, because the terms in the series are not all positive for ** C. ** no, because the series is not a geometric series** D. ** no, because the terms in the series are not recursively defined** E. ** no, because the function ** F. ** yes

**B.**
