Halfway Between 40 and 115

When you ask "What number is halfway between 40 and 115?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=115.

Halfway Between Line

To find the number halfway between 40 and 115, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 115 into our formula, we get:

(40 + 115)/2 = 77.5

Thus, the number halfway between 40 and 115 is 77.5.

To check that our answer is correct, we subtract 40 from 77.5 and subtract 77.5 from 115 and compare the two numbers:

77.5 - 40 = 37.5
115 - 77.5 = 37.5

As you can see, the halfway number is 37.5 higher than 40 and 37.5 lower than 115. Therefore, our halfway between answer of 77.5 above is correct.
