Arithmetic progression

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 arithmetic progression is
