Integer sequence

Support a children's charity online
In mathematics, an integer sequence is a sequence (i.e., an ordered list of terms) of integers.

An integer sequence may be specified explicitly by giving a formula for its n-th term, or implicitly by giving a relationship between its terms. For example, the sequence 0, 1, 1, 2, 3, 5, 8, 13, ... (the Fibonacci sequence) is formed by starting with 0 and 1 and then adding any two consecutive terms to obtain the next one: an implicit description. The sequence 0, 3, 8, 15, ... is formed according to the formula n2 − 1 for the n-th term: an explicit definition.

Integer sequences which have received their own name include:
