If you mean that the sum of two consecutive numbers should be 257, here are two ways to solve it:
1) Trial and error. Just try out different numbers; if the sum is too large, try again with smaller numbers; if the sum is too small, try again with larger numbers.
2) With algebra, you can get the result faster. Call the first number "x", then the second number is "x + 1". Thus, you get the equation:
x + (x + 1) = 257
Solve this for "x", and you get the first of the two consecutive numbers.

What are three consecutive numbers that sum to 771?
256, 257, 258 Let the three numbers be n-1, n, n+1, then: (n-1) + n + (n+1) = 771 → 3n = 771 → n = 257 → the three numbers are 257-1 = 256, 257 and 257+1 = 258
