Halfway Between 50 and 688

When you ask "What number is halfway between 50 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=50 and Y=688.

Halfway Between Line

To find the number halfway between 50 and 688, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 688 into our formula, we get:

(50 + 688)/2 = 369

Thus, the number halfway between 50 and 688 is 369.

To check that our answer is correct, we subtract 50 from 369 and subtract 369 from 688 and compare the two numbers:

369 - 50 = 319
688 - 369 = 319

As you can see, the halfway number is 319 higher than 50 and 319 lower than 688. Therefore, our halfway between answer of 369 above is correct.
