Convergents[x] gives if possible all convergents leading to the number x.The limit test, also sometimes known as the nth term test, says that if lima_n!=0 or this limit does not exist as n tends to infinity, then the series suma_n does not converge. For example, sum_(n=1)^(infty)(-1)^n does not converge by the limit test. The limit test is inconclusive when the limit is zero.$\begingroup$ SumConvergence does not have Comparison Test which Wolfram Alpha used to determine it convergence.
