Halfway Between 27 and 130

When you ask "What number is halfway between 27 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=27 and Y=130.

Halfway Between Line

To find the number halfway between 27 and 130, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 130 into our formula, we get:

(27 + 130)/2 = 78.5

Thus, the number halfway between 27 and 130 is 78.5.

To check that our answer is correct, we subtract 27 from 78.5 and subtract 78.5 from 130 and compare the two numbers:

78.5 - 27 = 51.5
130 - 78.5 = 51.5

As you can see, the halfway number is 51.5 higher than 27 and 51.5 lower than 130. Therefore, our halfway between answer of 78.5 above is correct.
