When you ask "What number is halfway between 81 and 136?" 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=136.
To find the number halfway between 81 and 136, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 81 and 136 into our formula, we get:
(81 + 136)/2 = 108.5
Thus, the number halfway between 81 and 136 is 108.5.
To check that our answer is correct, we subtract 81 from 108.5 and subtract 108.5 from 136 and compare the two numbers:
108.5 - 81 = 27.5
136 - 108.5 = 27.5
As you can see, the halfway number is 27.5 higher than 81 and 27.5 lower than 136. Therefore, our halfway between answer of 108.5 above is correct.
