When you ask "What number is halfway between 21 and 682?" 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=682.
To find the number halfway between 21 and 682, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 21 and 682 into our formula, we get:
(21 + 682)/2 = 351.5
Thus, the number halfway between 21 and 682 is 351.5.
To check that our answer is correct, we subtract 21 from 351.5 and subtract 351.5 from 682 and compare the two numbers:
351.5 - 21 = 330.5
682 - 351.5 = 330.5
As you can see, the halfway number is 330.5 higher than 21 and 330.5 lower than 682. Therefore, our halfway between answer of 351.5 above is correct.
