What is an arithmetic Sequence? An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed number to the previous term. WebA recursive rule gives the beginning term (s) of a sequence and a recursive equation that tells how an is related to one or more preceding terms.
