When you ask "What number is halfway between 18 and 590?" 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=590.
To find the number halfway between 18 and 590, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 18 and 590 into our formula, we get:
(18 + 590)/2 = 304
Thus, the number halfway between 18 and 590 is 304.
To check that our answer is correct, we subtract 18 from 304 and subtract 304 from 590 and compare the two numbers:
304 - 18 = 286
590 - 304 = 286
As you can see, the halfway number is 286 higher than 18 and 286 lower than 590. Therefore, our halfway between answer of 304 above is correct.
