When you ask "What number is halfway between 81 and 220?" 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=220.
To find the number halfway between 81 and 220, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 81 and 220 into our formula, we get:
(81 + 220)/2 = 150.5
Thus, the number halfway between 81 and 220 is 150.5.
To check that our answer is correct, we subtract 81 from 150.5 and subtract 150.5 from 220 and compare the two numbers:
150.5 - 81 = 69.5
220 - 150.5 = 69.5
As you can see, the halfway number is 69.5 higher than 81 and 69.5 lower than 220. Therefore, our halfway between answer of 150.5 above is correct.
