Does one belong to the set of even numbers?
Even numbers are numbers that are divisible by two. For example, number such as two, four, six, eight, 10, and so on. So we need to check, is one divisible by two?
If I would take one and divide it by two, we would get a fraction, one-half or 0.5. Therefore, one is not even. And since it’s not even, it must not belong to the set of even numbers. Therefore, our final answer will be no.
