Halfway Between 13 and 609

When you ask "What number is halfway between 13 and 609?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=609.

Halfway Between Line

To find the number halfway between 13 and 609, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 609 into our formula, we get:

(13 + 609)/2 = 311

Thus, the number halfway between 13 and 609 is 311.

To check that our answer is correct, we subtract 13 from 311 and subtract 311 from 609 and compare the two numbers:

311 - 13 = 298
609 - 311 = 298

As you can see, the halfway number is 298 higher than 13 and 298 lower than 609. Therefore, our halfway between answer of 311 above is correct.
