Halfway Between 45 and 634

When you ask "What number is halfway between 45 and 634?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=634.

Halfway Between Line

To find the number halfway between 45 and 634, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 634 into our formula, we get:

(45 + 634)/2 = 339.5

Thus, the number halfway between 45 and 634 is 339.5.

To check that our answer is correct, we subtract 45 from 339.5 and subtract 339.5 from 634 and compare the two numbers:

339.5 - 45 = 294.5
634 - 339.5 = 294.5

As you can see, the halfway number is 294.5 higher than 45 and 294.5 lower than 634. Therefore, our halfway between answer of 339.5 above is correct.
