Halfway Between 50 and 839

When you ask "What number is halfway between 50 and 839?" 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=839.

Halfway Between Line

To find the number halfway between 50 and 839, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 839 into our formula, we get:

(50 + 839)/2 = 444.5

Thus, the number halfway between 50 and 839 is 444.5.

To check that our answer is correct, we subtract 50 from 444.5 and subtract 444.5 from 839 and compare the two numbers:

444.5 - 50 = 394.5
839 - 444.5 = 394.5

As you can see, the halfway number is 394.5 higher than 50 and 394.5 lower than 839. Therefore, our halfway between answer of 444.5 above is correct.
