Halfway Between 50 and 831

When you ask "What number is halfway between 50 and 831?" 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=831.

Halfway Between Line

To find the number halfway between 50 and 831, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 831 into our formula, we get:

(50 + 831)/2 = 440.5

Thus, the number halfway between 50 and 831 is 440.5.

To check that our answer is correct, we subtract 50 from 440.5 and subtract 440.5 from 831 and compare the two numbers:

440.5 - 50 = 390.5
831 - 440.5 = 390.5

As you can see, the halfway number is 390.5 higher than 50 and 390.5 lower than 831. Therefore, our halfway between answer of 440.5 above is correct.
