What is an example of an odd number?

An odd number is defined as an integer that is not divisible by 2, meaning it leaves a remainder of 1 when divided by 2. When we look at the number 7, we can see that if we divide it by 2, the result is 3 with a remainder of 1, which confirms that 7 is indeed odd.

In contrast, the other numbers provided (4, 6, and 10) are all even, as they can be divided by 2 without leaving a remainder. For instance, dividing 4 by 2 results in 2, dividing 6 by 2 results in 3, and dividing 10 by 2 results in 5, all without remainders. This distinction makes 7 the only odd number among the choices provided.
