Best Answer: A recursive formula defines the value tn based on other values of the series. tn = a + (n-1)d is not recursive since tn increases by a fixed amount d which makes it an arithmetic sequence. You could write this recursively, though.

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.

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.
