Halfway Between 42 and 688

When you ask "What number is halfway between 42 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=42 and Y=688.

Halfway Between Line

To find the number halfway between 42 and 688, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 688 into our formula, we get:

(42 + 688)/2 = 365

Thus, the number halfway between 42 and 688 is 365.

To check that our answer is correct, we subtract 42 from 365 and subtract 365 from 688 and compare the two numbers:

365 - 42 = 323
688 - 365 = 323

As you can see, the halfway number is 323 higher than 42 and 323 lower than 688. Therefore, our halfway between answer of 365 above is correct.
