## Important Topics for Hall and Knight Higher Algebra Solutions Chapter 24: Recurring Series

**What is a Recurrence Relation?**

A recurrence relation is an equation that represents a rule-based sequence. It helps in finding the next term which is the subsequent term that depends upon the previous term or preceding term. In simple words, if in a given series a preceding term is given then we can easily find the subsequent term.

It is very well known that according to a standard pattern that all the terms in relation have similar characteristics. For eg- if we are given a value of ‘n’ we can easily determine other values by using the value of ‘n’.

**How to solve Recurrence Relations?**

In order to solve recurrence relations, it is important to find the initial term first. Here is an example of a sequence:

an = 2an-1-3an-2

- Now, first of all, we need to check the initial conditions a0 = 1, a1= 2 that the sequence is of closed patter.
- After this, try another initial condition and find a closed formula to it.
- After trying different initial conditions the result produces a series.
- Now, we will notice that the difference between each term also forms a sequence.
- We are required to add all the terms of the new sequence in order to understand which sequence is formed.
- If we understood the pattern it enables us to identify the initial condition of the recurrence relation.

**Examples of Recurrence Relations **

The examples of recurrence are based on series and sequence patterns. Following are a few examples we will discuss here:

**Factorial representation**

Factorial is defined by using the recurrence relation concept such as:

n! = n(n-1)!; n>0

When n = 0

0! = 1 is the initial condition

The factorial notation has to be expanded in order to find further values where the succeeding term is dependent upon the preceding term.

**Fibonacci numbers**

In series or Fibonacci numbers the last two preceding terms determine the succeeding terms.

Fn = fn-1 + fn-2

Take the initial values now,

f0= 0, f1= 1

So, f2 = f1 + f0 = 0+1 = 1

**What is a Recurrence Sequence?**

A sequence is an ordered set of quantities. Therefore in recurring relations, a recurring sequence is a sequence that satisfies recurrence relation. In the chapter, you will study different types of recurring sequence.
