Question

State cauchy's convergence criteria for sequence.​

Answer 1

Answer:

If a sequence (xn) converges then it satisfies the Cauchy's criterion: for ϵ > 0, there exists N such that |xn − xm| < ϵ for all n, m ≥ N. If a sequence converges then the elements of the sequence get close to the limit as n increases.
