What is the set of odd numbers between three and five?

Null set

Step-by-step explanation:

An odd number can be defined as an integer which can not divided exactly by 2. For instance: 1, 3, 5, 7, etc.

Here we are asked about the set of odd numbers which lies between 3 and 5. 3 and 5 are themselves but they will not be considered in the set since the question asks for odd numbers between 3 and 5.

It means 3 and 5 will be excluded. Rest we are left with only one number 4 which is even.

Therefore, the set of odd numbers between 3 and five will be a Null Set (having no numbers).
