Halfway Between 89 and 424

When you ask "What number is halfway between 89 and 424?" 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=424.

Halfway Between Line

To find the number halfway between 89 and 424, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 424 into our formula, we get:

(89 + 424)/2 = 256.5

Thus, the number halfway between 89 and 424 is 256.5.

To check that our answer is correct, we subtract 89 from 256.5 and subtract 256.5 from 424 and compare the two numbers:

256.5 - 89 = 167.5
424 - 256.5 = 167.5

As you can see, the halfway number is 167.5 higher than 89 and 167.5 lower than 424. Therefore, our halfway between answer of 256.5 above is correct.
