Halfway Between 49 and 509

When you ask "What number is halfway between 49 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=49 and Y=509.

Halfway Between Line

To find the number halfway between 49 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 49 and 509 into our formula, we get:

(49 + 509)/2 = 279

Thus, the number halfway between 49 and 509 is 279.

To check that our answer is correct, we subtract 49 from 279 and subtract 279 from 509 and compare the two numbers:

279 - 49 = 230
509 - 279 = 230

As you can see, the halfway number is 230 higher than 49 and 230 lower than 509. Therefore, our halfway between answer of 279 above is correct.
