There are infinitely many possible answers.
Select any number X, which may be positive or negative, rational or irrational (or even complex). And let Y = 68 - X.
Then the numbers X and Y will always sum to X + Y = X + 68 - X = 68.
Answer: The even numbers are 62, 64, 66, and 68
The two square numbers that add up to 225 are 144+81 = 225
71
2 numbers that add up to 8
62.5 and 37.5
68
137
5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 68
Answer: The even numbers are 62, 64, 66, and 68
There are no such whole numbers. The sum of three consecutive whole numbers must be a multiple of 3; as 68 is not a multiple of 3 (68 = 3 × 22 2/3) it cannot be the sum of three whole numbers.
137 and 11 are two prime numbers that add up to 148.
They are: 68+69+70 = 20768, 69 and 70.
No two prime numbers can add to 119.
The two square numbers that add up to 225 are 144+81 = 225
53 and 3 are two prime numbers that add up to 56
2 numbers that add up to 8
There are no two prime numbers that add up to be 152.
