Question

Remember that whole numbers that are next to each other, for example, 2 and 3, or 43, 44, and 45 are called consecutive numbers.

If n is the larger of two consecutive numbers, write an expression for the other number.

Answer 1

Given:

Whole numbers are next to each other and they are called consecutive numbers.

To find:

The expression for the other number if the larger of two consecutive numbers is n.

Solution:

According to the given definition, whole numbers are next to each other and they are called consecutive numbers. It means the difference between two consecutive interest is 1.

Larger number - Small number = 1

`n-\text{Smaller number}=1`

Add smaller number on both sides.

`n=1+\text{Smaller number}`

Subtract 1 from both sides.

`n-1=\text{Smaller number}`

Therefore, the expression for the other number is n-1.
