#### Question

Write first four terms of the A.P. when the first term a and the common differenced are given as follows a = 4, d = - 3

#### Solution

a = 4, d = - 3

Let the series be a1, a2, a3, a4

a1 = a = 4

a2 = a1 + d = 4 - 3 = 1

a3 = a2 + d = 1 - 3 = - 2

a4 = a3 + d = - 2 - 3 = - 5

Therefore, the series will be 4, 1, - 2 - 5 …

First four terms of this A.P. will be 4, 1, - 2 and - 5.

Is there an error in this question or solution?
