Halfway Between 47 and 509

When you ask "What number is halfway between 47 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=47 and Y=509.

Halfway Between Line

To find the number halfway between 47 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 47 and 509 into our formula, we get:

(47 + 509)/2 = 278

Thus, the number halfway between 47 and 509 is 278.

To check that our answer is correct, we subtract 47 from 278 and subtract 278 from 509 and compare the two numbers:

278 - 47 = 231
509 - 278 = 231

As you can see, the halfway number is 231 higher than 47 and 231 lower than 509. Therefore, our halfway between answer of 278 above is correct.
