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= -2, d=0

Given: a = -2 and d = 0


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


So, the first term a is -2 and the common difference d is 0, then the first four terms of the AP is


-2, (-2+0), (-2+2×0), (-2+3×0)


⇒ -2, -2, -2, -2


Hence, the first four terms of the A.P. is -2, -2, -2 and -2.
