2 consecutive numbers for 257?

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.
