k starts at 1 and sum goes to infinity

since 1/k is diverging and its limit is infinity, why does the series converge ? isnt it necessary for an alternating series to go strictly to 0 as k approaches infinity to be a convergent series ?

1/k does not diverge to infinity, it converges to 0

so the harmonic series does diverge while the alternating harmonic series converge ?
