Halfway Between 50 and 639

When you ask "What number is halfway between 50 and 639?" 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=639.

Halfway Between Line

To find the number halfway between 50 and 639, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 639 into our formula, we get:

(50 + 639)/2 = 344.5

Thus, the number halfway between 50 and 639 is 344.5.

To check that our answer is correct, we subtract 50 from 344.5 and subtract 344.5 from 639 and compare the two numbers:

344.5 - 50 = 294.5
639 - 344.5 = 294.5

As you can see, the halfway number is 294.5 higher than 50 and 294.5 lower than 639. Therefore, our halfway between answer of 344.5 above is correct.
