Definition 0.1. A sequence X = (xn) in R is said to converge to x E R, or x is said to be a limit of (xif for every e > 0 there exists a natural number Ke N such that for all n > K, the terms Tn satisfy x,n - x| < e. If a sequence has a limit, we say that the sequence is convergent; if it has no limit, we...
