Halfway Between 88 and 518

When you ask "What number is halfway between 88 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=88 and Y=518.

Halfway Between Line

To find the number halfway between 88 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 518 into our formula, we get:

(88 + 518)/2 = 303

Thus, the number halfway between 88 and 518 is 303.

To check that our answer is correct, we subtract 88 from 303 and subtract 303 from 518 and compare the two numbers:

303 - 88 = 215
518 - 303 = 215

As you can see, the halfway number is 215 higher than 88 and 215 lower than 518. Therefore, our halfway between answer of 303 above is correct.
