# Write an A.P. whose first term is a and common difference is d in each of the following.a = 10, d = 5

a = 10, d = 5

Let a1 = a = 10

Since, the common difference d = 5

Using formula an + 1 = an + d

Thus, a2 = a1 + d = 10 + 5 = 15

a3 = a2 + d = 15 + 5 = 20

a4 = a3 + d = 20 + 5 = 25

Hence, An A.P with common difference 5 is 10, 15, 20, 25,….
