Halfway Between 20 and 120

When you ask "What number is halfway between 20 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=20 and Y=120.

Halfway Between Line

To find the number halfway between 20 and 120, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 120 into our formula, we get:

(20 + 120)/2 = 70

Thus, the number halfway between 20 and 120 is 70.

To check that our answer is correct, we subtract 20 from 70 and subtract 70 from 120 and compare the two numbers:

70 - 20 = 50
120 - 70 = 50

As you can see, the halfway number is 50 higher than 20 and 50 lower than 120. Therefore, our halfway between answer of 70 above is correct.
