When p = 1/2 the p -series looks like this: Because p ≤ 1, this series diverges. To see why it diverges, notice that when n is a square number, say n = k2, the n th term equals. So this p -series includes every term in the harmonic series plus many more terms. Because the harmonic series is divergent, this series is also divergent.
