Write first four terms of the A.P. when the first term a and the common differenced are given as follows a = 10, d = 10 - Mathematics

Write first four terms of the A.P. when the first term a and the common differenced are given as follows a = 10, d = 10

a = 10, d = 10

Let the series be a₁, a₂, a₃, a₄, a₅ …

a₁ = a = 10

a₂ = a₁ + d = 10 + 10 = 20

a₃ = a₂ + d = 20 + 10 = 30

a₄ = a₃ + d = 30 + 10 = 40

a₅ = a₄ + d = 40 + 10 = 50

Therefore, the series will be 10, 20, 30, 40, 50 …

First four terms of this A.P. will be 10, 20, 30, and 40.
