Question
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
✓
Answer
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,….
