Halfway Between 89 and 280

When you ask "What number is halfway between 89 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=89 and Y=280.

Halfway Between Line

To find the number halfway between 89 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 280 into our formula, we get:

(89 + 280)/2 = 184.5

Thus, the number halfway between 89 and 280 is 184.5.

To check that our answer is correct, we subtract 89 from 184.5 and subtract 184.5 from 280 and compare the two numbers:

184.5 - 89 = 95.5
280 - 184.5 = 95.5

As you can see, the halfway number is 95.5 higher than 89 and 95.5 lower than 280. Therefore, our halfway between answer of 184.5 above is correct.
