Write first four terms of the A.P. when the first term a and the common difference d are given as follows:
a = -1.25, d = -0.25
उत्तर
a = -1.25, d = -0.25
Let the series be a1, a2, a3, a4 …
a1 = a = -1.25
a2 = a1 + d = -1.25 + (-0.25) = -1.50
a3 = a2 + d = -1.50 + (-0.25) = -1.75
a4 = a3 + d = -1.75 + (-0.25) = -2.0
Clearly, the series will be -1.25, -1.50, -1.75, -2.0 ……..
First four terms of this A.P. will be -1.25, -1.50, -1.75 and -2.0.
