When you ask "What number is halfway between 66 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=66 and Y=129.
To find the number halfway between 66 and 129, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 66 and 129 into our formula, we get:
(66 + 129)/2 = 97.5
Thus, the number halfway between 66 and 129 is 97.5.
To check that our answer is correct, we subtract 66 from 97.5 and subtract 97.5 from 129 and compare the two numbers:
97.5 - 66 = 31.5
129 - 97.5 = 31.5
As you can see, the halfway number is 31.5 higher than 66 and 31.5 lower than 129. Therefore, our halfway between answer of 97.5 above is correct.
