To test $$k$=0$$2$k$6$k$-4$ for convergence you could compare it to $$k$=0$$(13)$k and use the limit comparison test.

Begin that process by computing the limit below.

limk$$$2$k$6$k$-4(13)$k$=$

Based on this limit and what you know about $$k$=0$$(13)$k$,$ what does the limit comparison test tell you about $$k$=0$$2$k$6$k$-4?$
