Halfway Between 1 and 518

When you ask "What number is halfway between 1 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=1 and Y=518.

Halfway Between Line

To find the number halfway between 1 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 518 into our formula, we get:

(1 + 518)/2 = 259.5

Thus, the number halfway between 1 and 518 is 259.5.

To check that our answer is correct, we subtract 1 from 259.5 and subtract 259.5 from 518 and compare the two numbers:

259.5 - 1 = 258.5
518 - 259.5 = 258.5

As you can see, the halfway number is 258.5 higher than 1 and 258.5 lower than 518. Therefore, our halfway between answer of 259.5 above is correct.
