## Introduction to the Concept

- Recurrence Relations are a recursive definitions of a mathematical functions or sequences.
*for example:*

*g(n) = g(n-1) + 2n – 1*

*g(0) = 0*

- this defines function f(n) = n^2, and the recurrence relation:

*f(n) = f(n-1) + f(n-2)*

*f(1) = 1*

*f(0) = 0*

## Solving a Recurrence Relation

- There are many techniques to solve Recurrence Relations, the main techniques are
(also known as expansion or unfolding method) and the*Iteration Method*method.**Master Theorem** *In this post we’ll talk about***Iteration Method Continue reading**
