The alternating harmonic series has partial sums approaching ln 2 from alternating sides. The alternating-series test gives sufficient conditions: nonnegative magnitudes decrease to zero. Monotonicity is not necessary for every convergent alternating series, and a finite plot alone is not a convergence proof.
