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.
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.
2*4 + 3*x = 34
