Halfway Between 50 and 851

When you ask "What number is halfway between 50 and 851?" 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=851.

Halfway Between Line

To find the number halfway between 50 and 851, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 851 into our formula, we get:

(50 + 851)/2 = 450.5

Thus, the number halfway between 50 and 851 is 450.5.

To check that our answer is correct, we subtract 50 from 450.5 and subtract 450.5 from 851 and compare the two numbers:

450.5 - 50 = 400.5
851 - 450.5 = 400.5

As you can see, the halfway number is 400.5 higher than 50 and 400.5 lower than 851. Therefore, our halfway between answer of 450.5 above is correct.
