[Equation goes here - download the original to see it.] is a null sequence if, for every positive number [Equation goes here - download the original to see it.] there exists an integer N such that [Equation] . If is not necessary for [Equation] for a sequence to be null. Sequences (1) and (2) above are null sequences. In neither of them does any element of the sequence actually take a zero value. Sequence (3) is not null. Further examples (4) [Equation] (5) [Equation] (6) [Equation] (7) [Equation]
