The sum of the first n n terms of an arithmetic progression is.
A 1 3 the first term is 3 a n a n 1 2 add 2 to the previous term. The number d is called the common difference because any two consecutive terms of an arithmetic sequence differ by d and it is found by subtracting any pair of terms anand. An arithmetic progression is a sequence where each term except the first term is obtained by adding a fixed number to its previous term. A 3 the first term d 5 the common difference Using the Arithmetic Sequence rule.
