What is the result if you pick a number from 1 to 9 and add this to the next higher number and add 9 and divide by 2 and subtract your starting number?

For the numbers 1 thru 9, the result is always 5. In fact, the result is 5 for any integer, and if you change the wording slightly to say 'add this to the original number plus 1' instead of 'add this to the next higher number' the result is 5 for ANY complex number. Here's why: Number picked: x Next higher number (for integers) or Number picked plus 1 (for any other sort of number): x + 1 Add them: x + x + 1 = 2x + 1 Add 9: 2x + 1 + 9 = 2x + 10 Divide by 2: x + 5 Subtract starting number: x + 5 - x = 5.
