Diverges by the Limit Comparison Test Due to the simplicity of the series, we can use the Limit Comparison Test, which tells us if we have some positive sequence b_n and we know the convergence or divergence of sumb_n, then if c=lim_(n->oo)a_n/b_n>0 ne oo, then both series either converge or diverge. We can easily see that the series is not convergent, since: lim_ (n->oo) (-1)^n != 0 We can take a closer look at the partial sums: sum_ (n=1)^oo (-1)^n s_1 = -1 s_2 =0 s_3 = -1 and we can prove by induction that: { (s_ (2n) = 0), (s_ (2n+1) = -1):} so that partial sums oscillate between the two values and do
