Halfway Between 13 and 679

When you ask "What number is halfway between 13 and 679?" 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=679.

Halfway Between Line

To find the number halfway between 13 and 679, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 679 into our formula, we get:

(13 + 679)/2 = 346

Thus, the number halfway between 13 and 679 is 346.

To check that our answer is correct, we subtract 13 from 346 and subtract 346 from 679 and compare the two numbers:

346 - 13 = 333
679 - 346 = 333

As you can see, the halfway number is 333 higher than 13 and 333 lower than 679. Therefore, our halfway between answer of 346 above is correct.
