The 8th term of an AP is 17 and its 14th term is 29. The common difference of the AP is
Given: a8 = 17
a14 = 29
To find: common difference = d
Consider a8 = 17
⇒ a + 7d = 17 …………….(1)
Consider a14 = 29
⇒ a + 13d = 29 …………….(2)
Subtracting equation (1) from equation (2), we get,
6d = 12
⇒ d = 2
∴ Common difference = 2
