1.	Let the sum of the 3 consecutive terms in AP be 180 then midlle of those 3 terms would be ________(a) 60(b) 80(c) 90(d) 179The question was asked in an interview for job.This key question is from Arithmetic Sequences in division Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» The correct choice is (a) 60 Easy EXPLANATION: Let a1, b1, C1 be three TERMS, then a1 + b1 + c1 = 180, a1 + c1 = 2b1(A M property), 3B1 = 180, b1=60.
