Halfway Between 15 and 679

When you ask "What number is halfway between 15 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=15 and Y=679.

Halfway Between Line

To find the number halfway between 15 and 679, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 679 into our formula, we get:

(15 + 679)/2 = 347

Thus, the number halfway between 15 and 679 is 347.

To check that our answer is correct, we subtract 15 from 347 and subtract 347 from 679 and compare the two numbers:

347 - 15 = 332
679 - 347 = 332

As you can see, the halfway number is 332 higher than 15 and 332 lower than 679. Therefore, our halfway between answer of 347 above is correct.
