This seems like a fairly easy problem, but i'm not getting the book's answer.
The sum from x=1 to infinity of 2x^2-1/3x^5+2x+1
The book seems to expunge enough to make a reference series 1/x^3, which is a p-series. I just don't see how you can expunge that much..
The question is as written in the book and asks: Use the Limit Comp. Test to determine the convergence or divergence of the series. No parenthesis are needed. the ^ implies something raised to a power.
