Arithmetic progression is a kind of common sequence.

A sequence is called an arithmetic sequence if the difference between each term and its predecessor, starting with the second term, is equal to the same constant.

This constant is called the tolerance of the arithmetic series, and the tolerance is often denoted by the letter d.

For example, the following sequence is an arithmetic sequence:

1,3,5,7,9……1+2(n-1)

The general term formula for arithmetic progression is:

an=a1+(n-1)d

The first n terms and formula are:

Sn=n(a1+an)/2

Note: The above n is a positive integer.
