Recurrence relations are often used to model the cost of recursive functions. For example, the standard Mergesort takes a list of size n, splits it in half, performs Mergesort on each half, and finally merges the two sublists in n steps. The cost for this can be modeled as. T ( n) = 2 T ( n / 2) + n.

We can define the factorial by using the concept of recurrence relation, such as; n!=n(n-1)! ; n>0 When n = 0, 0! = 1 is the initial condition.
