Halfway Between 85 and 438

When you ask "What number is halfway between 85 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=85 and Y=438.

Halfway Between Line

To find the number halfway between 85 and 438, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 438 into our formula, we get:

(85 + 438)/2 = 261.5

Thus, the number halfway between 85 and 438 is 261.5.

To check that our answer is correct, we subtract 85 from 261.5 and subtract 261.5 from 438 and compare the two numbers:

261.5 - 85 = 176.5
438 - 261.5 = 176.5

As you can see, the halfway number is 176.5 higher than 85 and 176.5 lower than 438. Therefore, our halfway between answer of 261.5 above is correct.
