When you ask "What number is halfway between 81 and 218?" 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=218.
To find the number halfway between 81 and 218, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 81 and 218 into our formula, we get:
(81 + 218)/2 = 149.5
Thus, the number halfway between 81 and 218 is 149.5.
To check that our answer is correct, we subtract 81 from 149.5 and subtract 149.5 from 218 and compare the two numbers:
149.5 - 81 = 68.5
218 - 149.5 = 68.5
As you can see, the halfway number is 68.5 higher than 81 and 68.5 lower than 218. Therefore, our halfway between answer of 149.5 above is correct.
