Hey guys, for some reason I am really struggling with the whole limit and direct comparison tests for series. Many times, I can't decide what to compare my series with.
For example: (I am currently stuck on) -- the series from 2 to infinity of 2 / 7n ln(n)+4n
I am assuming that I would use the limit comparison test (right??), which I am thinking would be ln(n)/n (a divergent series), and then divide An/Bn as limit goes to infinity? So then I am thinking the answer would be divergent?
Appreciate any feedback, thanks
Which means 2 over 7n times ln(n) plus 4.
Would I use the limit comparison test of say ln(n)/n? Then I am assuming it would be divergent.
