ARITHMETIC SEQUENCE

Arithmetic sequences follow an addition rule that allows you to predict what the next term will be. The following equations are for the nth term of an arithmetic sequence where an is the nth term, n is the number of the term, and d is the common difference.

Explicit: Recursive:

an = a1 + d(n − 1) an = an − 1 + d
