Halfway Between 31 and 679

When you ask "What number is halfway between 31 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=31 and Y=679.

Halfway Between Line

To find the number halfway between 31 and 679, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 679 into our formula, we get:

(31 + 679)/2 = 355

Thus, the number halfway between 31 and 679 is 355.

To check that our answer is correct, we subtract 31 from 355 and subtract 355 from 679 and compare the two numbers:

355 - 31 = 324
679 - 355 = 324

As you can see, the halfway number is 324 higher than 31 and 324 lower than 679. Therefore, our halfway between answer of 355 above is correct.
