Just a few questions...

1. Does the series for (n)/(n+5) from 0 to infinity converge or diverge? If so by which test (P-test, limit comparison test, integral test, etc)

and

2. Does the series for ((-1)^n)(n/(5n-4)) from 0 to infinity converge or diverge? If so by which test? (alternating series, absolute convergence, etc)



Show off your math knowledge here, I know you've been waiting for an opportunity! biggrin.gif

Help is much appreciated, thanks friends!

i won't tell you the direct answer
but the first one you can determine by the nth term divergence test

and the second one by alternating series
>.<

good luck
