Halfway Between 5 and 509

When you ask "What number is halfway between 5 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=5 and Y=509.

Halfway Between Line

To find the number halfway between 5 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 509 into our formula, we get:

(5 + 509)/2 = 257

Thus, the number halfway between 5 and 509 is 257.

To check that our answer is correct, we subtract 5 from 257 and subtract 257 from 509 and compare the two numbers:

257 - 5 = 252
509 - 257 = 252

As you can see, the halfway number is 252 higher than 5 and 252 lower than 509. Therefore, our halfway between answer of 257 above is correct.
