  • The numbers which are continuously following each other in the order of smallest to greatest are called consecutive numbers.

Example :

Numbers like 101, 102, 103, 104, …etc are called consecutive numbers.

Here we will discuss 3 - digit numbers. We start counting three-digit numbers from 100.

Smallest Three-Digit Number

  • The greatest two-digit number is 99 and 100 comes just after 99.
  • 3-Digit numbers start from 100. It is the smallest 3-digit number.
  • The number 100 is important for counting. We can represent 100 as a group to make counting easy.

Examples:

   100 can be represented using a 10 by 10 chocolate bar.
