A sequence is called a Cauchy sequence if the terms of the sequence eventually all become arbitrarily close to one another. That is, given > 0 there exists N such that if m, n > N then |am- an| < .

A sequence $x_0, x_1, x_2, \dots$ in a metric space $(X,d)$ is a Cauchy sequence if, for every real number $\epsilon > 0$ , there exists a natural number $N$ such that $d(x_n,x_m) < \epsilon$ whenever $n,m > N$ .
