Halfway Between 50 and 909

When you ask "What number is halfway between 50 and 909?" 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=909.

Halfway Between Line

To find the number halfway between 50 and 909, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 909 into our formula, we get:

(50 + 909)/2 = 479.5

Thus, the number halfway between 50 and 909 is 479.5.

To check that our answer is correct, we subtract 50 from 479.5 and subtract 479.5 from 909 and compare the two numbers:

479.5 - 50 = 429.5
909 - 479.5 = 429.5

As you can see, the halfway number is 429.5 higher than 50 and 429.5 lower than 909. Therefore, our halfway between answer of 479.5 above is correct.
