Halfway Between 50 and 821

When you ask "What number is halfway between 50 and 821?" 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=821.

Halfway Between Line

To find the number halfway between 50 and 821, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 821 into our formula, we get:

(50 + 821)/2 = 435.5

Thus, the number halfway between 50 and 821 is 435.5.

To check that our answer is correct, we subtract 50 from 435.5 and subtract 435.5 from 821 and compare the two numbers:

435.5 - 50 = 385.5
821 - 435.5 = 385.5

As you can see, the halfway number is 385.5 higher than 50 and 385.5 lower than 821. Therefore, our halfway between answer of 435.5 above is correct.
