Halfway Between 43 and 688

When you ask "What number is halfway between 43 and 688?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=43 and Y=688.

Halfway Between Line

To find the number halfway between 43 and 688, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 688 into our formula, we get:

(43 + 688)/2 = 365.5

Thus, the number halfway between 43 and 688 is 365.5.

To check that our answer is correct, we subtract 43 from 365.5 and subtract 365.5 from 688 and compare the two numbers:

365.5 - 43 = 322.5
688 - 365.5 = 322.5

As you can see, the halfway number is 322.5 higher than 43 and 322.5 lower than 688. Therefore, our halfway between answer of 365.5 above is correct.
