Halfway Between 4 and 513

When you ask "What number is halfway between 4 and 513?" 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=513.

Halfway Between Line

To find the number halfway between 4 and 513, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 513 into our formula, we get:

(4 + 513)/2 = 258.5

Thus, the number halfway between 4 and 513 is 258.5.

To check that our answer is correct, we subtract 4 from 258.5 and subtract 258.5 from 513 and compare the two numbers:

258.5 - 4 = 254.5
513 - 258.5 = 254.5

As you can see, the halfway number is 254.5 higher than 4 and 254.5 lower than 513. Therefore, our halfway between answer of 258.5 above is correct.
