Halfway Between 90 and 422

When you ask "What number is halfway between 90 and 422?" 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=422.

Halfway Between Line

To find the number halfway between 90 and 422, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 422 into our formula, we get:

(90 + 422)/2 = 256

Thus, the number halfway between 90 and 422 is 256.

To check that our answer is correct, we subtract 90 from 256 and subtract 256 from 422 and compare the two numbers:

256 - 90 = 166
422 - 256 = 166

As you can see, the halfway number is 166 higher than 90 and 166 lower than 422. Therefore, our halfway between answer of 256 above is correct.
