Q. 4 A5.0( 1 Vote )

Write the first four terms of the A.P. when first term a and common difference d are given as follows:

a = 1, d = 1

Answer :

Given: a = 1 and d = 1

The general form of an A.P is a, a+d, a+2d, a+3d,…

So, the first term a is 1 and the common difference d is 1, then the first four terms of the AP is

1, (1+1), (1+2×1), (1+3×1)

1, 2, 3, 4

Hence, the first four terms of the A.P. is 1, 2, 3 and 4.
