To summarize the process of writing a recursive formula for an arithmetic sequence: 1. Determine if the sequence is arithmetic (Do you add, or subtract, the same amount from one term to the next?2. Find the common difference.The number you add or subtract.

Recursive Formula. For a sequence a 1, a 2, a 3, . . . , a n, . . . a recursive formula is a formula that requires the computation of all previous terms in order to find the value of a n. Note: Recursion is an example of an iterative procedure.

While recursive sequences are easy to understand, they are difficult to deal with, in that, in order to get, say, the thirty-nineth term in this sequence, you would first have to find terms one through thirty-eight. There isn't a formula into which you could plug n = 39 and get the answer.

How to Solve Recurrence Relations. In trying to find a formula for some mathematical sequence, a common intermediate step is to find the nth term, not as a function of n, but in terms of earlier terms of the sequence. For example, while...
