Recursion is an example of an iterative procedure. And so we just get 12. The formula which involves the previous term and the common ratio.
Recursion is one of the fundamental tools of computer science.
The factorial function written n is defined as. For the third term we subtract seven twice. Then a recursive formula for this sequence will be needed to compute all the previous terms and find the value of t n. A recursive formula is a formula that requires the computation of all previous terms in order to find the value of a n.
