When you ask "What number is halfway between 21 and 482?" 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=482.
To find the number halfway between 21 and 482, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 21 and 482 into our formula, we get:
(21 + 482)/2 = 251.5
Thus, the number halfway between 21 and 482 is 251.5.
To check that our answer is correct, we subtract 21 from 251.5 and subtract 251.5 from 482 and compare the two numbers:
251.5 - 21 = 230.5
482 - 251.5 = 230.5
As you can see, the halfway number is 230.5 higher than 21 and 230.5 lower than 482. Therefore, our halfway between answer of 251.5 above is correct.
