Recurrence relations are mathematical expressions that define sequences by relating each term to its predecessors. They are crucial for understanding patterns within sequences, such as the Fibonacci sequence. The text delves into the order and degree of these relations, the importance of initial conditions, and the quest for closed-form solutions. Techniques like mathematical induction and the Characteristic Root Technique are discussed for solving complex relations and finding explicit formulas.
