Question

How do you do recursive formulas

Answer 1

Find the common difference.

Explanation:

Answer 2

To write a recursive formula you need to: First, determine if the sequence is geometric(For example, If your multiply, or divide, the same amount for one term or more). Next, Find the common ratio(In other words the number that you multiply or divide). Finally, we make a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
