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.
