When you ask "What number is halfway between 18 and 831?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=831.
To find the number halfway between 18 and 831, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 18 and 831 into our formula, we get:
(18 + 831)/2 = 424.5
Thus, the number halfway between 18 and 831 is 424.5.
To check that our answer is correct, we subtract 18 from 424.5 and subtract 424.5 from 831 and compare the two numbers:
424.5 - 18 = 406.5
831 - 424.5 = 406.5
As you can see, the halfway number is 406.5 higher than 18 and 406.5 lower than 831. Therefore, our halfway between answer of 424.5 above is correct.
