**What are whole numbers?**

**Let us first understand what whole numbers are. **

Numbers 0,1,2,3,4,5,6…… and so on are whole numbers.

When we say Successor and Predecessor of a number, the number in focus is a whole number.

**Let’s learn the meaning of Successor and Predecessor of a number**

## **What do we mean by the Predecessor of a whole number? **

The number that comes just before a number is called the Predecessor.

*For Example*,

The **Predecessor** of 100 is 99. Here, 99 **comes just before **100.

So, the **Predecessor **of a given number is **one less than **the given number. We can observe that 99 is **one less than** 100, so 99 is the **Predecessor** of 100.

## **What do we mean by the Successor of a whole number? **

The number that comes just before a number is called the Successor.

*For Example,*

The **Successor **of 100 is 101. Here, 101 **comes just after **100.

So, the **Successor** of a given number is **one more than **the given number. We can observe that 101 is **one more than** 100, so 101 is the **Successor** of 100.

**Interesting observation **

If the Successor of 99 is 100, then 99 is Predecessor of 100.

**How do you find the Successor of a number?**

The Successor of any number is obtained by adding 1 to the number.

*For Example, *

99 +1 = 100; therefore, 100 is the Successor of 99.

The number which comes immediately after a particular number is called its Successor.

**We observe that every whole number has its Successor.**

Number + 1 = Successor

## How do you find the Predecessor of a number?

The Predecessor of any number is obtained by subtracting 1 from the number.

*For Example, *

100 -1 = 99; therefore, 99 is the Predecessor of 100

Number - 1 = Predecessor

**We observe that every number other than zero has its Predecessor. The whole number 0 does not have any predecessor.**

**What is the Successor of 100 and Predecessor of 100?**

Successor of 100 = 100+1=101 ( 101 comes just after 100)

Predecessor of 100 = 100-1 = 99 ( 99 comes just before 100)
