Halfway Between 90 and 518

When you ask "What number is halfway between 90 and 518?" 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=518.

Halfway Between Line

To find the number halfway between 90 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 518 into our formula, we get:

(90 + 518)/2 = 304

Thus, the number halfway between 90 and 518 is 304.

To check that our answer is correct, we subtract 90 from 304 and subtract 304 from 518 and compare the two numbers:

304 - 90 = 214
518 - 304 = 214

As you can see, the halfway number is 214 higher than 90 and 214 lower than 518. Therefore, our halfway between answer of 304 above is correct.
