When you ask "What number is halfway between 84 and 129?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=84 and Y=129.
To find the number halfway between 84 and 129, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 84 and 129 into our formula, we get:
(84 + 129)/2 = 106.5
Thus, the number halfway between 84 and 129 is 106.5.
To check that our answer is correct, we subtract 84 from 106.5 and subtract 106.5 from 129 and compare the two numbers:
106.5 - 84 = 22.5
129 - 106.5 = 22.5
As you can see, the halfway number is 22.5 higher than 84 and 22.5 lower than 129. Therefore, our halfway between answer of 106.5 above is correct.
