Halfway Between 63 and 509

When you ask "What number is halfway between 63 and 509?" 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=509.

Halfway Between Line

To find the number halfway between 63 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 63 and 509 into our formula, we get:

(63 + 509)/2 = 286

Thus, the number halfway between 63 and 509 is 286.

To check that our answer is correct, we subtract 63 from 286 and subtract 286 from 509 and compare the two numbers:

286 - 63 = 223
509 - 286 = 223

As you can see, the halfway number is 223 higher than 63 and 223 lower than 509. Therefore, our halfway between answer of 286 above is correct.
