Halfway Between 20 and 130

When you ask "What number is halfway between 20 and 130?" 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=130.

Halfway Between Line

To find the number halfway between 20 and 130, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 130 into our formula, we get:

(20 + 130)/2 = 75

Thus, the number halfway between 20 and 130 is 75.

To check that our answer is correct, we subtract 20 from 75 and subtract 75 from 130 and compare the two numbers:

75 - 20 = 55
130 - 75 = 55

As you can see, the halfway number is 55 higher than 20 and 55 lower than 130. Therefore, our halfway between answer of 75 above is correct.
