Halfway Between 5 and 513

When you ask "What number is halfway between 5 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=5 and Y=513.

Halfway Between Line

To find the number halfway between 5 and 513, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 513 into our formula, we get:

(5 + 513)/2 = 259

Thus, the number halfway between 5 and 513 is 259.

To check that our answer is correct, we subtract 5 from 259 and subtract 259 from 513 and compare the two numbers:

259 - 5 = 254
513 - 259 = 254

As you can see, the halfway number is 254 higher than 5 and 254 lower than 513. Therefore, our halfway between answer of 259 above is correct.
