Sequence
In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.
Formally, a sequence can be defined as a function whose domain is either the set of the natural numbers (for infinite sequences), or the set of the first n natural numbers (for a sequence of finite length n).
2.2 Finite and infinite
See also: ω-language
The length of a sequence is defined as the number of terms in the sequence.
A sequence of a finite length n is also called an n-tuple.
