= Integer sequence
An <integer sequence> is a <sequence> whose terms are <integers>. It can be specified by a formula, a <recurrence relation>, a counting interpretation or a finite computational rule. Examples include $a_n=n^2$, the <Fibonacci numbers> and the <prime numbers>.
A finite prefix does not determine a unique infinite sequence. If a <polynomial> matches $a_0,\ldots,a_N$, adding $c\prod_{j=0}^N(x-j)$ leaves those values unchanged and usually changes later ones. Identifying a sequence therefore requires its definition, indexing convention and domain, rather than a few suggestive values alone.
