Halfway Between 90 and 520

When you ask "What number is halfway between 90 and 520?" 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=520.

Halfway Between Line

To find the number halfway between 90 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 520 into our formula, we get:

(90 + 520)/2 = 305

Thus, the number halfway between 90 and 520 is 305.

To check that our answer is correct, we subtract 90 from 305 and subtract 305 from 520 and compare the two numbers:

305 - 90 = 215
520 - 305 = 215

As you can see, the halfway number is 215 higher than 90 and 215 lower than 520. Therefore, our halfway between answer of 305 above is correct.
