WebIf the sum of first n terms of an A.P is given by Sn = 3n^2 + 4n. Determine the A.P and the nth term ← Prev Question Next Question → +1 vote 41.5k views asked Sep 30, 2024 in Mathematics by Samantha (39.3k points) If the sum of first n terms of an A.P is given by Sn = 3n 2 + 4n. Determine the A.P and the n th term arithmetic progression cbse WebLet a be the first term and d be the common difference. We know that, sum of first n terms = S n = n 2 [2a + (n − 1)d] It is given that sum of the first n terms of an A.P. is 3n2 + 6n. ∴ First term = a = S 1 = 3(1) 2 + 6(1) = 9. Sum of first two terms = S 2 = 3(2) 2 + 6(2) = 24. ∴ Second term = S 2 − S 1 = 24 − 9 = 15. ∴ Common difference = d = Second term − First …
