When you ask "What number is halfway between 18 and 630?" 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=630.
To find the number halfway between 18 and 630, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 18 and 630 into our formula, we get:
(18 + 630)/2 = 324
Thus, the number halfway between 18 and 630 is 324.
To check that our answer is correct, we subtract 18 from 324 and subtract 324 from 630 and compare the two numbers:
324 - 18 = 306
630 - 324 = 306
As you can see, the halfway number is 306 higher than 18 and 306 lower than 630. Therefore, our halfway between answer of 324 above is correct.
