Halfway Between 81 and 179

When you ask "What number is halfway between 81 and 179?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=81 and Y=179.

Halfway Between Line

To find the number halfway between 81 and 179, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 81 and 179 into our formula, we get:

(81 + 179)/2 = 130

Thus, the number halfway between 81 and 179 is 130.

To check that our answer is correct, we subtract 81 from 130 and subtract 130 from 179 and compare the two numbers:

130 - 81 = 49
179 - 130 = 49

As you can see, the halfway number is 49 higher than 81 and 49 lower than 179. Therefore, our halfway between answer of 130 above is correct.
