$\displaystyle \displaystyle\Sigma(-1)^n*\frac{3n}{4n-1}$

I tried the A.S.T. but I can't get past how to figure out whether A_(n+1) < A_n. I found out that it doesn't converge absolutely using the absolute convergence & the nth term test. I tried the ratio test but I get a limit of 1..which tells me nothing about the convergence. Can someone explain what would be the best test to use bc I cannot figure it out. Thanks
