Halfway Between 1 and 679

When you ask "What number is halfway between 1 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=1 and Y=679.

Halfway Between Line

To find the number halfway between 1 and 679, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 679 into our formula, we get:

(1 + 679)/2 = 340

Thus, the number halfway between 1 and 679 is 340.

To check that our answer is correct, we subtract 1 from 340 and subtract 340 from 679 and compare the two numbers:

340 - 1 = 339
679 - 340 = 339

As you can see, the halfway number is 339 higher than 1 and 339 lower than 679. Therefore, our halfway between answer of 340 above is correct.
