Assuming you mean how to solve what three consecutive numbers sum to some value:
Divide the sum by three to get the middle number.
The other two numbers are one less than this and one more than it.
example:
Which three consecutive numbers sum to 108?
108 ÷ 3 = 36
→ The other two numbers are 36 - 1 = 35 and 36 + 1 = 37
→ The three numbers are 35, 36, 37.
35 + 36 + 37 = 108 as required.

In fact, they can. 2 and 3 are consecutive prime numbers.For larger numbers, one of two consecutive numbers will always be even, and therefore, not a prime.In fact, they can. 2 and 3 are consecutive prime numbers.For larger numbers, one of two consecutive numbers will always be even, and therefore, not a prime.In fact, they can. 2 and 3 are consecutive prime numbers.For larger numbers, one of two consecutive numbers will always be even, and therefore, not a prime.In fact, they can. 2 and 3 are consecutive prime numbers.For larger numbers, one of two consecutive numbers will always be even, and therefore, not a prime.
2 and 3 are the only consecutive prime numbers.
3 can't lie between consecutive whole numbers. It lies between 2 and 4, which are consecutive even numbers.
The sum of 3 consecutive whole numbers is always equal to 3 times the middle number in that sequence.
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.
