27 2+7 = 9 X 3 = 27
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.

3x^2 + 6
3x+2
3x + (x-2) ----> 3x + x - 2 = 4x - 2, so the answer is four times the number, minus 2.
If: 2+3x = 77 Then: x = 25
2x3=6+4=10 2.

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.
2*4 + 3*x = 34
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
