Watching series converge (or not)

Pick a series, press play, and watch the partial sums Sₙ build up while the matching test reads out its verdict.

Partial sums Sₙ

Size of each term |aₙ| (bars), ratio |aₙ₊₁/aₙ| (line), comparison series (dots)

n = 1

Partial sum Sₙ–

Latest term aₙ–

Ratio |aₙ₊₁/aₙ|–

Root |aₙ|^(1/n)–
