# The 17th term of an AP exceeds its 10th term by 21. The common difference of the AP isA. 3B. 2C. - 3D. - 2

|

Let a be the first term and d be the common difference.

Given: a17 = a10 + 21

To find: common difference = d

Consider a17 = a10 + 21

a + 16d = a + 9d + 21

16d = 9d + 21

16d - 9d = 21

7d = 21

d = 3

Common difference = 3
