How do you find the recursive formula

WebTo find the recursive formula for the given sequence, write it in the tabular form. Hence, the recursive formula in function notation is given as: f (1) = 3 , f (n)= 2. f (n-1) In subscript … WebA recursive formula allows us to find any term of an arithmetic sequence using a function of the preceding term. Each term is the sum of the previous term and the common difference. For example, if the common difference is 5, then each term is the previous term plus 5. As with any recursive formula, the first term must be given.
