Q4 of 176 Page 9

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

a = 1, d = 0.1

Given: a = 1 and d = 0.1


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 0.1, then the first four terms of the AP is


1, (1+0.1), (1+2×(0.1)), (1+3×(0.1))


⇒ 1, 1.1, 1.2, 1.3


Hence, the first four terms of the A.P. is 1, 1.1, 1.2 and 1.3.
