Halfway Between 40 and 120

When you ask "What number is halfway between 40 and 120?" 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=120.

Halfway Between Line

To find the number halfway between 40 and 120, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 120 into our formula, we get:

(40 + 120)/2 = 80

Thus, the number halfway between 40 and 120 is 80.

To check that our answer is correct, we subtract 40 from 80 and subtract 80 from 120 and compare the two numbers:

80 - 40 = 40
120 - 80 = 40

As you can see, the halfway number is 40 higher than 40 and 40 lower than 120. Therefore, our halfway between answer of 80 above is correct.
