No, there is 6, 12, 18, 24 and so on so forth. Only half of them are odd.

We have three consecutive odd integers, To make it easy, I am going to choose the one in the middle to be called X. Therefore, the first odd integer will be called (X-2) and the third odd integer will be called (X+2). The fourth odd integer will be called (X+4).So the sum of the first three, is (X-2) + (X) + (X+2) or X+X+X -2 +2 this equals 3X.Then, 3X -18 equals the fourth odd integer which is (X+4), so 3X - 18 = X + 4Subtract an X from each side for 2X - 18 = 4. Add 18 to each side for 2X = 22. Solve for X, X equals 11. So the first consecutive odd integer is 11-2 or 9, the third is 11+2 or 13 and the fourth is X + 4 or 15. To Check, 9 + 11 + 13 = 33. 15 + 18 = 33

44=41+3 46=41+5 24=11+13 18=11+7

You cannot. The sum of 5 odd numbers is always odd. 30 is not odd.

The given numbers are all odd. The sum of 5 odd numbers must be odd. 50 is not odd so there is no solution.

Here is one possible way: 2 * 1.25 2 * 1.5 5 * 2.5 It is a very odd way of doing it because, in so doing, none of the cows will remain alive. Suppose you could partition the 18 cows into 9 odd groups. Now, Odd + Odd = Even Even + Even = Even and Even + Odd = Odd So, Odd + Odd + Odd + Odd + Odd + Odd + Odd + Odd + Odd = 18 => Even + Even + Even + Even + Odd = 18 => Even + Even + Odd = 18 => Even + Odd = 18 => Odd = 18 which is false. Therefore, it is impossible to partition 18 cows into 9 odd groups.

It is not odd because it is an even number

18 is an even number. not an odd one

9

9

because it is a even number

18

You might answer this in a couple of different ways. 11 is the "odd" one, as it is the only "odd" number, while 4, 12 and 18 are all "even".

18 is an even number.

18 is even bcause you can divide it by 2. 18/2=9

Even numbers are divisible by 2. 18/2=9, therefore it is an even number.
