1.	If the n^thterm of the AP is 2n + 7, then the common difference will be _____(a) -2(b) 2(c) 3(d) -3This question was posed to me by my college director while I was bunking the class.This question is from Nth Term of Arithmetic Progression in division Arithmetic Progressions of Mathematics – Class 10
Answer» RIGHT option is (b) 2 To elaborate: n^th TERM of the AP is 2n + 7 Tn = 2n + 7 Common DIFFERENCE = T2 – T1 = (2 × 2 + 7 – (2 × 1 + 7)) = 11 – 9 = 2
