WebWhat is the Sum of n Terms of an AP Formula? The sum of n terms of an AP can be found using one of the following formulas: S n = n/2 (2a+(n−1)d) S n = n/2 (a 1 +a n) Here, a = a 1 = the first term, d = the common difference, n … WebFormula 1: The sum of first n terms of an arithmetic sequence where nth n th term is not known is given by: Sn = n 2 [2a +(n− 1)d] S n = n 2 [ 2 a + ( n − 1) d] Where Sn S n = the sum of the arithmetic sequence, a = the first term, d = the common difference between the terms, n = the total number of terms in the sequence and
