1.	In A.P. 171, 162, 153, ………. Find first negative term.(a) 0(b) -2(c) -6(d) -9I got this question by my school teacher while I was bunking the class.The query is from Arithmetic Progression(A.P.) topic in portion Sequences and Series of Mathematics – Class 11
Answer» Right option is (d) -9 For EXPLANATION I would say: a=171 and d=162-171 = -9. an<0 =>171+(N-1) (-9) < 0 =>180-9n < 0 =>9n > 180 =>n > 20 => n=21 for first negative term. First negative term is 171+(20) (-9) = 171-180 = -9
