Halfway Between 63 and 513

When you ask "What number is halfway between 63 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=63 and Y=513.

Halfway Between Line

To find the number halfway between 63 and 513, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 63 and 513 into our formula, we get:

(63 + 513)/2 = 288

Thus, the number halfway between 63 and 513 is 288.

To check that our answer is correct, we subtract 63 from 288 and subtract 288 from 513 and compare the two numbers:

288 - 63 = 225
513 - 288 = 225

As you can see, the halfway number is 225 higher than 63 and 225 lower than 513. Therefore, our halfway between answer of 288 above is correct.
