When you ask "What number is halfway between 81 and 982?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=81 and Y=982.
To find the number halfway between 81 and 982, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 81 and 982 into our formula, we get:
(81 + 982)/2 = 531.5
Thus, the number halfway between 81 and 982 is 531.5.
To check that our answer is correct, we subtract 81 from 531.5 and subtract 531.5 from 982 and compare the two numbers:
531.5 - 81 = 450.5
982 - 531.5 = 450.5
As you can see, the halfway number is 450.5 higher than 81 and 450.5 lower than 982. Therefore, our halfway between answer of 531.5 above is correct.
