    Show that if Sum(a_n) diverges, and k does not equal 0, then Sum(k*a_n) diverges

    i mean this is common sense, constant*infinity = infinity..

    diverges doesn't necessarily mean infinity.

    show the contrapositive if Sum(k*a_n) converges then Sum(a_n) converges.

    Sum(k*a_n) converges so s=Sum(k*a_n) =ksum(a_n) k not zero then sum(a_n)=s/k
