WebLearn how to find recursive formulas for arithmetic sequences. For example, find the recursive formula of 3, 5, 7,... Before taking this lesson, make sure you are familiar with … WebEach successive term is multiplied by 3, so for any term n (where n>=1), its denominator would be 3^(n-1). Then notice that every numerator is 4 less than its denominator, so the formula for the numerator would be 3^(n-1) - 4. Putting these together, the terms of the sequence would be represented by the formula ( 3^(n-1) - 4 ) / 3^(n-1) where n>=1. chorcom 2023
