Answer 1

Sum of an even and an odd number:

The sum of an even number and odd number is always odd.

The following examples verify the fact:

• $2+3=5$ ($2$ is even and $3$ is odd but their sum i.e. $5$ is odd)
• $10+21=31$ ($10$ is even and $21$ is odd but their sum i.e. $31$ is odd)

Hence, the sum of an even and an odd number is always odd.
