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
An = a1 + d(n - 1)
The sum of the first n terms Sn of arithmetic sequence can be expressed as
Sn = n(a1 + an )/2
