It is always an odd number

If you're adding an odd number of numbers, if two are even and one is odd, you will get an odd number as a result. Three odds are odd. If two are odd and one is even, you have an even result. Three evens are even.

The sum of an odd and even number is always odd because there's always one left over. Think of any odd number as being any even number plus one. If you add two even numbers, the answer is always even. If you add an even and an odd (plus one), the answer is always odd.

One is an odd number.

The 4 is even. The 5 is odd. Their sum, 9, is odd. The sum of (one even number) + (one odd number) is always odd.

Yes. One has to be the square of an odd number. The other square has to the the square of the even number either before or after the odd number. If this is confusing just plug in real values. In either case, an odd times and odd is odd. Therefore one of the squares has to be odd. AN even times an even, however, is always even. Therefore, the second square has to be even. Thus, one of the squares is even and the other is odd. An even plus and odd is always odd.

One is an odd number

One is the first odd number

There is only one number and it is odd.

An odd number.

odd

No two consecutive numbers have a product that is an even number. Any two consecutive numbers include one odd number and one even number. The product of one odd number and one even number is always an odd number.

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 1 is an odd number.

Any pair of one even and one odd number will have an even product and an odd sum.

They have only one thing in common. By adding 1 to either an even number or an odd number makes them opposite. (even becomes odd and odd becomes even).

that's an odd question. One is an odd number.

To determine the even or oddness of a number we look at the last digit, in this case it is a one which is an odd number. This makes the number an odd number.

No, it is not.

Any odd number can be written as an even number plus one. Any even number plus any other even number makes an even number. Add one makes an odd number. So an odd number plus an even number is always an odd number. Algebraically, any odd number can be written as 2a+ 1 where a is a whole number. Any even number can be written as 2b, where b is a whole number. Add them together, the sum is 2(a + b) + 1, which is odd.

This answer cannot be answered because two consecutive numbers consist of one odd number and one even number, and the sum of an odd number plus an even number is always an odd number.

Odd. All numbers ending in one are odd.
