Always on point, very user friendly, and very useful. WebRemember that a sequence is like a list of numbers, while a series is a sum of that list. Notice that a sequence converges if the limit as n approaches infinity of An equals a constant number, like 0, 1, pi, or -33. However, if that limit goes to +-infinity, then the sequence is divergent .

WebHow do you tell if a function is convergent or divergent? If we say that a sequence converges, it means that the limit of the sequence exists as n → ∞ n\to\infty n→∞. If the limit of the sequence as n → ∞ n\to\infty n→∞ does not exist, we say that the sequence diverges. Is 0 convergent or divergent? 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).
