As the positive integer ${\textstyle n}$ becomes larger and larger, the value ${\textstyle n\times \sin \left({\tfrac {1}{n}}\right)}$ becomes arbitrarily close to ${\textstyle 1}$ . We say that "the limit of the sequence ${\textstyle n\times \sin \left({\tfrac {1}{n}}\right)}$ equals ${\textstyle 1}$ ."

In mathematics, the limit of a sequence is the value that the terms of a sequence "tend to", and is often denoted using the $\lim$ symbol (e.g., $\lim _{n\to \infty }a_{n}$ ).^[1] If such a limit exists and is finite, the sequence is called convergent.^[2] A sequence that does not converge is said to be divergent.^[3] The limit of a sequence is said to be the fundamental notion on which the whole of mathematical analysis ultimately rests.^[1]

Limits can be defined in any metric or topological space, but are usually first encountered in the real numbers.
