1.

(Sum of nh term of AP is1s.

Answer»

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on.

Thus nth term of an APseriesis Tn= a + (n - 1) d, where Tn= nthterm and a = first term.

Here d = common difference = Tn- Tn-1.

The sum of n terms is also equal to the formula where l is the last term.
