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.
Well, darling, the numbers 11, 12, and 17 add up to 40, which is a multiple of 10. So, there you have it, sweetie, those three numbers fit the bill. Now go forth and impress someone with your math skills, honey!
76 + 77 + 78 three numbers in a row
That isn't possible. The three consecutive number are assumed to be integers; the sum of three consecutive integers is always a multiple of 3 (try it out).
Cubes of numbers are made by multiplying a number by itself three times.

That doesn't work. The number has to be divisible by three. Any three consecutive numbers add up to a multiple of three.
Only if they are odd.
1, 2 and 7.
To make 20 with three different odd numbers, we can use the numbers 1, 7, and 12. 1 + 7 + 12 = 20. These numbers are odd because they cannot be evenly divided by 2. It's important to note that there are multiple combinations of three odd numbers that can add up to 20, such as 3 + 9 + 8 or 5 + 11 + 4.
You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).You add the numbers.

Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).
There are multiple ways to add three numbers together to get a sum of 17. One possible combination is 5 + 6 + 6, another is 9 + 4 + 4, and yet another is 7 + 5 + 5.
They are: 17+23+29 = 69
