WebQuestion 1154461: If an= 27 , a1= -12 and d=3 find n Found 2 solutions by josgarithmetic, ikleyn: Answer by josgarithmetic(38299) (Show Source): You can put this solution on YOUR website!-----If an= 27 , a1= -12 and d=3 find n----- You are given . Just substitute and solve. WebSubtracting equation (i) from (ii), we get a + 14d = 87 a + 9d = 57 – – – 5d = 30 ∴ d = 30 5 = 6 Substituting d = 6 in equation (i), we get a + 9 (6) = 57 ∴ a + 54 = 57 ∴ a = 57 – 54 = 3 t 21 = a + (21 – 1)d = a + 20d = 3 + 20 (6) = 3 + 120 ∴ t 21 = 123 Concept: Arithmetic Progression Is there an error in this question or solution?

WebKey Takeaways. An arithmetic sequence is a sequence where the difference d between successive terms is constant. The general term of an arithmetic sequence can be written in terms of its first term a1, common difference d, and index n as follows: an = a1 + (n − 1)d. An arithmetic series is the sum of the terms of an arithmetic sequence. how does fabletics shipWebMar 31, 2024 · If in an A.P a=2 and d=3 then find s12 Advertisement Answer 12 people found it helpful misspayal66 Answer: S12 = n/2 (2a+ (12-1)d =12/6 (2*2+ (11*3) =2 (4+33) =2*37 =74 ans Find Math textbook solutions?
