Halfway Between 90 and 538

When you ask "What number is halfway between 90 and 538?" 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=538.

Halfway Between Line

To find the number halfway between 90 and 538, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 538 into our formula, we get:

(90 + 538)/2 = 314

Thus, the number halfway between 90 and 538 is 314.

To check that our answer is correct, we subtract 90 from 314 and subtract 314 from 538 and compare the two numbers:

314 - 90 = 224
538 - 314 = 224

As you can see, the halfway number is 224 higher than 90 and 224 lower than 538. Therefore, our halfway between answer of 314 above is correct.
