## Explicit Formulas for Geometric Sequences

How to write recursive formula. If you know the nth term and the common ratio , r , of a geometric sequence , you can find the (n+1)th term using the recursive formula. an+1=an?r .Recursive   ## Sequences as Functions

Using the first term as the starting point and the formula as the previous term plus the common difference, construct a recursive formula. a1= first term;a n=an -1+d. a1= the first
