When you ask "What number is halfway between 21 and 418?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=418.
To find the number halfway between 21 and 418, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 21 and 418 into our formula, we get:
(21 + 418)/2 = 219.5
Thus, the number halfway between 21 and 418 is 219.5.
To check that our answer is correct, we subtract 21 from 219.5 and subtract 219.5 from 418 and compare the two numbers:
219.5 - 21 = 198.5
418 - 219.5 = 198.5
As you can see, the halfway number is 198.5 higher than 21 and 198.5 lower than 418. Therefore, our halfway between answer of 219.5 above is correct.
