Halfway Between 4 and 518

When you ask "What number is halfway between 4 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=4 and Y=518.

Halfway Between Line

To find the number halfway between 4 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 518 into our formula, we get:

(4 + 518)/2 = 261

Thus, the number halfway between 4 and 518 is 261.

To check that our answer is correct, we subtract 4 from 261 and subtract 261 from 518 and compare the two numbers:

261 - 4 = 257
518 - 261 = 257

As you can see, the halfway number is 257 higher than 4 and 257 lower than 518. Therefore, our halfway between answer of 261 above is correct.
