Halfway Between 45 and 684

When you ask "What number is halfway between 45 and 684?" 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=684.

Halfway Between Line

To find the number halfway between 45 and 684, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 684 into our formula, we get:

(45 + 684)/2 = 364.5

Thus, the number halfway between 45 and 684 is 364.5.

To check that our answer is correct, we subtract 45 from 364.5 and subtract 364.5 from 684 and compare the two numbers:

364.5 - 45 = 319.5
684 - 364.5 = 319.5

As you can see, the halfway number is 319.5 higher than 45 and 319.5 lower than 684. Therefore, our halfway between answer of 364.5 above is correct.
