Halfway Between 11 and 669

When you ask "What number is halfway between 11 and 669?" 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=669.

Halfway Between Line

To find the number halfway between 11 and 669, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 669 into our formula, we get:

(11 + 669)/2 = 340

Thus, the number halfway between 11 and 669 is 340.

To check that our answer is correct, we subtract 11 from 340 and subtract 340 from 669 and compare the two numbers:

340 - 11 = 329
669 - 340 = 329

As you can see, the halfway number is 329 higher than 11 and 329 lower than 669. Therefore, our halfway between answer of 340 above is correct.
