Halfway Between 90 and 424

When you ask "What number is halfway between 90 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=90 and Y=424.

Halfway Between Line

To find the number halfway between 90 and 424, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 424 into our formula, we get:

(90 + 424)/2 = 257

Thus, the number halfway between 90 and 424 is 257.

To check that our answer is correct, we subtract 90 from 257 and subtract 257 from 424 and compare the two numbers:

257 - 90 = 167
424 - 257 = 167

As you can see, the halfway number is 167 higher than 90 and 167 lower than 424. Therefore, our halfway between answer of 257 above is correct.
