![]() d = The common difference (the difference between every term and its previous term).Įxamples Using Arithmetic Sequence Recursive FormulaĮxample 1: Find the recursive formula of the arithmetic sequence 1, 5/4, 3/2, 7/4, ….a n−1 = (n – 1) th term of the arithmetic sequence (which is the previous term of the n th term).a n = n th term of the arithmetic sequence.The arithmetic sequence recursive formula is: Thus, the arithmetic sequence recursive formula is: Arithmetic Sequence Recursive Formula As we learned in the previous section that every term of an arithmetic sequence is obtained by adding a fixed number (known as the common difference, d) to its previous term. Recursion in the case of an arithmetic sequence is finding one of its terms by applying some fixed logic on its previous term. What Is Arithmetic Sequence Recursive Formula? Let us learn the arithmetic sequence recursive formula along with a few solved examples. This fixed number is usually known as the common difference and is denoted by d. For example, -1, 1, 3, 5, … is an arithmetic sequence as every term is obtained by adding a fixed number 2 to its previous term. ![]() It is a sequence of numbers in which every successive term is obtained by adding a fixed number to its previous term. Therefore, the recursive formula should look as follows: Arithmetic Sequence Recursive Formulaīefore going to learn the arithmetic sequence recursive formula, let us recall what is an arithmetic sequence. ![]()
