Final answer:
The number 17 is odd because it has a remainder of 1 when divided by 2, and its last digit is 7, which is not an even digit.
Step-by-step explanation:
The number 17 is an odd number. An odd number is any integer which cannot be divided evenly by 2. In the case of 17, when it is divided by 2, it results in 8 with a remainder of 1. Conversely, an even number is any integer that can be divided evenly by 2, which is not the case with 17. To easily determine if a number is odd or even, you can look at the last digit of the number: if it is 0, 2, 4, 6, or 8, then the number is even; if it is 1, 3, 5, 7, or 9, it is odd. Since the last digit of 17 is 7, we can conclusively say that 17 is odd.
To determine if a number is odd or even, we need to look at its ones place. If the digit in the ones place is 1, 3, 5, 7, or 9, the number is odd. If the digit in the ones place is 0, 2, 4, 6, or 8, the number is even.
In this case, the number is 17. The digit in the ones place is 7, which is odd. Therefore, the number 17 is odd.
