Halfway Between 89 and 438

When you ask "What number is halfway between 89 and 438?" 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=438.

Halfway Between Line

To find the number halfway between 89 and 438, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 438 into our formula, we get:

(89 + 438)/2 = 263.5

Thus, the number halfway between 89 and 438 is 263.5.

To check that our answer is correct, we subtract 89 from 263.5 and subtract 263.5 from 438 and compare the two numbers:

263.5 - 89 = 174.5
438 - 263.5 = 174.5

As you can see, the halfway number is 174.5 higher than 89 and 174.5 lower than 438. Therefore, our halfway between answer of 263.5 above is correct.
