Halfway Between 31 and 120

When you ask "What number is halfway between 31 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=31 and Y=120.

Halfway Between Line

To find the number halfway between 31 and 120, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 120 into our formula, we get:

(31 + 120)/2 = 75.5

Thus, the number halfway between 31 and 120 is 75.5.

To check that our answer is correct, we subtract 31 from 75.5 and subtract 75.5 from 120 and compare the two numbers:

75.5 - 31 = 44.5
120 - 75.5 = 44.5

As you can see, the halfway number is 44.5 higher than 31 and 44.5 lower than 120. Therefore, our halfway between answer of 75.5 above is correct.
