Halfway Between 50 and 817

When you ask "What number is halfway between 50 and 817?" 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=817.

Halfway Between Line

To find the number halfway between 50 and 817, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 817 into our formula, we get:

(50 + 817)/2 = 433.5

Thus, the number halfway between 50 and 817 is 433.5.

To check that our answer is correct, we subtract 50 from 433.5 and subtract 433.5 from 817 and compare the two numbers:

433.5 - 50 = 383.5
817 - 433.5 = 383.5

As you can see, the halfway number is 383.5 higher than 50 and 383.5 lower than 817. Therefore, our halfway between answer of 433.5 above is correct.
