Answer:
Even numbers are numbers that can be broken in half equally while still being a whole number, whilst odd numbers tend to not be divisible by 2.
Step-by-step explanation:
For example, 4 is an even number because half of 4 is 2, which is a whole number that's divisible by 2
But 3 is an odd number due to its half being 1.5, which isn't a whole number nor divisible by 2.
