Successor and Predecessor of
4-Digit Number

We will learn the successor and predecessor of four digit number.

The number that comes just after a given number is called the successor of the given number. For example 1028 comes just after 1027. So 1028 is the successor of 1027.

For example:

1. The successor of 1271 is 1272.

2. The successor of 7643 is 7644.

The number that comes just before a given number is called the predecessor of the given number. For example 2336 comes just before 2337. So the predecessor of 2337 is 2336.

For example:

1. The predecessor of 2876 is 2875.

2. The predecessor of 5414 is 5413.

Important questions and answers on successor and predecessor of four digit number:

1. What is the predecessor of the smallest 4-digit number?

We know, the smallest 4-digit number is 1000.

999 comes just before 1000.

So, the predecessor of the smallest 4-digit number is 999.

2. What is the successor of the greatest 4-digit number?

We know, the greatest 4-digit number is 9999

10000 comes just after 9999.

So, the successor of the greatest 4-digit number is 10000 (i.e., 5-digit number).

3. What is the successor of 9998?

To find the successor of the given number i.e., 9998 we need to add 1 to 9998 (1 + 9998)

So, 9999 comes just after 9998.

The successor of 9998 is 9999 which is the greatest 4-digit number.

4. What is the predecessor of 1001?

To find the predecessor of the given number i.e., 1001 we need to subtract 1 from 1001 (1001 - 1)

So, 1000 comes just before 1001.

The predecessor of 1001 is 1000 which is the smallest 4-digit number.
