Halfway Between 10 and 518

When you ask "What number is halfway between 10 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=10 and Y=518.

Halfway Between Line

To find the number halfway between 10 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 518 into our formula, we get:

(10 + 518)/2 = 264

Thus, the number halfway between 10 and 518 is 264.

To check that our answer is correct, we subtract 10 from 264 and subtract 264 from 518 and compare the two numbers:

264 - 10 = 254
518 - 264 = 254

As you can see, the halfway number is 254 higher than 10 and 254 lower than 518. Therefore, our halfway between answer of 264 above is correct.
