Halfway Between 90 and 528

When you ask "What number is halfway between 90 and 528?" 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=528.

Halfway Between Line

To find the number halfway between 90 and 528, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 528 into our formula, we get:

(90 + 528)/2 = 309

Thus, the number halfway between 90 and 528 is 309.

To check that our answer is correct, we subtract 90 from 309 and subtract 309 from 528 and compare the two numbers:

309 - 90 = 219
528 - 309 = 219

As you can see, the halfway number is 219 higher than 90 and 219 lower than 528. Therefore, our halfway between answer of 309 above is correct.
