Halfway Between 81 and 280

When you ask "What number is halfway between 81 and 280?" 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=280.

Halfway Between Line

To find the number halfway between 81 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 81 and 280 into our formula, we get:

(81 + 280)/2 = 180.5

Thus, the number halfway between 81 and 280 is 180.5.

To check that our answer is correct, we subtract 81 from 180.5 and subtract 180.5 from 280 and compare the two numbers:

180.5 - 81 = 99.5
280 - 180.5 = 99.5

As you can see, the halfway number is 99.5 higher than 81 and 99.5 lower than 280. Therefore, our halfway between answer of 180.5 above is correct.
