Halfway Between 11 and 609

When you ask "What number is halfway between 11 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=11 and Y=609.

Halfway Between Line

To find the number halfway between 11 and 609, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 609 into our formula, we get:

(11 + 609)/2 = 310

Thus, the number halfway between 11 and 609 is 310.

To check that our answer is correct, we subtract 11 from 310 and subtract 310 from 609 and compare the two numbers:

310 - 11 = 299
609 - 310 = 299

As you can see, the halfway number is 299 higher than 11 and 299 lower than 609. Therefore, our halfway between answer of 310 above is correct.
