When you ask "What number is halfway between 87 and 173?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=87 and Y=173.
To find the number halfway between 87 and 173, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 87 and 173 into our formula, we get:
(87 + 173)/2 = 130
Thus, the number halfway between 87 and 173 is 130.
To check that our answer is correct, we subtract 87 from 130 and subtract 130 from 173 and compare the two numbers:
130 - 87 = 43
173 - 130 = 43
As you can see, the halfway number is 43 higher than 87 and 43 lower than 173. Therefore, our halfway between answer of 130 above is correct.
