Halfway Between 13 and 671

When you ask "What number is halfway between 13 and 671?" 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=671.

Halfway Between Line

To find the number halfway between 13 and 671, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 671 into our formula, we get:

(13 + 671)/2 = 342

Thus, the number halfway between 13 and 671 is 342.

To check that our answer is correct, we subtract 13 from 342 and subtract 342 from 671 and compare the two numbers:

342 - 13 = 329
671 - 342 = 329

As you can see, the halfway number is 329 higher than 13 and 329 lower than 671. Therefore, our halfway between answer of 342 above is correct.
