Question

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

Solution

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.

  Is there an error in this question or solution?
