Halfway Between 15 and 675

When you ask "What number is halfway between 15 and 675?" 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=675.

Halfway Between Line

To find the number halfway between 15 and 675, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 675 into our formula, we get:

(15 + 675)/2 = 345

Thus, the number halfway between 15 and 675 is 345.

To check that our answer is correct, we subtract 15 from 345 and subtract 345 from 675 and compare the two numbers:

345 - 15 = 330
675 - 345 = 330

As you can see, the halfway number is 330 higher than 15 and 330 lower than 675. Therefore, our halfway between answer of 345 above is correct.
