"WebThe divergence test is a conditional if-then statement. If the antecedent of the divergence test fails (i.e. the sequence does converge to zero) then the series may or may not converge. For example, Σ1/n is the famous harmonic series which diverges but Σ1/ (n^2) converges by the p-series test (it converges to (pi^2)/6 for any curious minds). " - The nth term of an ap is 3n – 2
