Their sum is three times the middle number.

The sum of three consecutive whole numbers is equal to three times the middle number. For example, if the middle number is "x", then the sum is equal to x + (x - 1) + (x + 1), which simplifies to 3x.

Since 57/3 = 19, we know that the middle number has to be 19. The other numbers will be the numbers contiguous to 19. Therefore, the three consecutive numbers which add up to 57 are: 18 + 19 + 20 = 57

The middle number must be one third of 39, ie 13. The other numbers are thus 11 and 15.

That doesn't work. The number has to be divisible by three. Any three consecutive numbers add up to a multiple of three.

The sum of 3 consecutive whole numbers is always equal to 3 times the middle number in that sequence.

The sum of three consecutive whole numbers is equal to three times the middle number. For example, if the middle number is "x", then the sum is equal to x + (x - 1) + (x + 1), which simplifies to 3x.

EVERY three consecutive numbers add to a multiple of 3: Proof: numbers are n, n + 1 and n + 2. The total is 3n + 3 or 3(n + 1) This means that for any three consecutive numbers, the total is 3 times the middle number.

Since 57/3 = 19, we know that the middle number has to be 19. The other numbers will be the numbers contiguous to 19. Therefore, the three consecutive numbers which add up to 57 are: 18 + 19 + 20 = 57

The smallest consecutive three numbers that total 120 are... 39, 40 & 41.

Divide 72 by 3, this equals 24. This is the middle of the three numbers, so the answer is 23, 24 and 25. This works with finding any odd amount of consecutive numbers that sum up to another number.

Any three consecutive integers are divisible by three because it can be shown that the sum divided by three is the middle number.

-- method -- We need X numbers which are consecutive, so the middle number will be 1/ X of the total. Divide the sum of the numbers by the number of numbers ... in this case divide 186 by 3. The numbers are to be consecutive and even, so subtract 2 from the number go get one of the numbers and add 2 to the number to get the other number. You now have three numbers which are even and consecutive. Now, place a minus sign in front of them, to turn them into negative numbers For instance 12, 14 and 16 are three consecutive numbers whose sum is 42. -12, -14 and - 16 are three consecutive even integers whose sum is -42 Now you know all you need to solve the problem.

The middle number must be one third of 39, ie 13. The other numbers are thus 11 and 15.
