Halfway Between 45 and 130

When you ask "What number is halfway between 45 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=45 and Y=130.

Halfway Between Line

To find the number halfway between 45 and 130, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 130 into our formula, we get:

(45 + 130)/2 = 87.5

Thus, the number halfway between 45 and 130 is 87.5.

To check that our answer is correct, we subtract 45 from 87.5 and subtract 87.5 from 130 and compare the two numbers:

87.5 - 45 = 42.5
130 - 87.5 = 42.5

As you can see, the halfway number is 42.5 higher than 45 and 42.5 lower than 130. Therefore, our halfway between answer of 87.5 above is correct.
