Halfway Between 90 and 530

When you ask "What number is halfway between 90 and 530?" 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=530.

Halfway Between Line

To find the number halfway between 90 and 530, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 530 into our formula, we get:

(90 + 530)/2 = 310

Thus, the number halfway between 90 and 530 is 310.

To check that our answer is correct, we subtract 90 from 310 and subtract 310 from 530 and compare the two numbers:

310 - 90 = 220
530 - 310 = 220

As you can see, the halfway number is 220 higher than 90 and 220 lower than 530. Therefore, our halfway between answer of 310 above is correct.
