# Arithmetic progression

##### This online calculator computes last nth term of arithmetic progression and sum of the members

Definition:

*Arithmetic progression* is a sequence, such as the positive odd integers 1, 3, 5, 7, . . . , in which each term after the first is formed by adding a constant to the preceding term.

This constant difference is called *common difference*.

Given this, each member of progression can be expressed as

Sum of the n members of arithmeic progression is
