Halfway Between 2 and 688

When you ask "What number is halfway between 2 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=2 and Y=688.

Halfway Between Line

To find the number halfway between 2 and 688, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 688 into our formula, we get:

(2 + 688)/2 = 345

Thus, the number halfway between 2 and 688 is 345.

To check that our answer is correct, we subtract 2 from 345 and subtract 345 from 688 and compare the two numbers:

345 - 2 = 343
688 - 345 = 343

As you can see, the halfway number is 343 higher than 2 and 343 lower than 688. Therefore, our halfway between answer of 345 above is correct.
