WebOct 18, 2024 · If the sequence of partial sums converges to a real number S, the infinite series converges. If we can describe the convergence of a series to S, we call S the sum of the series, and we write ∞ ∑ n = 1an = S. If the sequence of partial sums diverges, we have the divergence of a series. WebOct 28, 2014 · If ( s n) converges to s, then s is called the limit of the sequence ( s n) and we write l i m n → ∞ s n = s. If a sequence does not converge to a real number, it is said to diverge." I understand the meaning of convergence and divergence but I am a little bit unsure about using this definition to prove the statements.
