An AP is a sequence of numbers such that the difference between the consecutive numbers is the same. The first term of an Ap is denoted as 'a'
and the common difference is represented as 'd'.

The general form of an Ap is = a, a+d, a+2d, a+3d,...
The nth term of an AP with the first term 'a' and common difference ' is
an = a+(n-1)d.

The Sum of the first n terms of an AP is given by S=n\2[2a+(n-1)d]
