Question

Write first four terms of the A.P. when the first term a and the common difference d are given as follows:
(i) a = 10, d = 10​

Answer 1

(i) a = 10, d = 10

Let us consider, the Arithmetic Progression 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

And so on

Therefore, the A.P. series will be 10, 20, 30, 40, 50.

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