Halfway Between 99 and 439

When you ask "What number is halfway between 99 and 439?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=99 and Y=439.

Halfway Between Line

To find the number halfway between 99 and 439, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 439 into our formula, we get:

(99 + 439)/2 = 269

Thus, the number halfway between 99 and 439 is 269.

To check that our answer is correct, we subtract 99 from 269 and subtract 269 from 439 and compare the two numbers:

269 - 99 = 170
439 - 269 = 170

As you can see, the halfway number is 170 higher than 99 and 170 lower than 439. Therefore, our halfway between answer of 269 above is correct.
