Halfway Between 55 and 120

When you ask "What number is halfway between 55 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=55 and Y=120.

Halfway Between Line

To find the number halfway between 55 and 120, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 120 into our formula, we get:

(55 + 120)/2 = 87.5

Thus, the number halfway between 55 and 120 is 87.5.

To check that our answer is correct, we subtract 55 from 87.5 and subtract 87.5 from 120 and compare the two numbers:

87.5 - 55 = 32.5
120 - 87.5 = 32.5

As you can see, the halfway number is 32.5 higher than 55 and 32.5 lower than 120. Therefore, our halfway between answer of 87.5 above is correct.
