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

Answer 1

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.
