Arithmetic progression sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant. Arithmetic progression is a sequence, such as the positive even integers 2, 4, 6, 8,10, 12, . . . in which each term after the first is formed by adding a constant (common difference) to the preceding term.
each member of progression can be expressed as

A

The sum of the first n terms S
