WebAn 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. WebIf the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d, then the nth term of the sequence is given by: a n = a 1 + (n - 1)d. The sum of the first n terms S n of an arithmetic sequence is calculated by the following formula: S n = n (a 1 + a n )/2 = n [2a 1 + (n - 1)d]/2.
