Halfway Between 11 and 622

When you ask "What number is halfway between 11 and 622?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=622.

Halfway Between Line

To find the number halfway between 11 and 622, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 622 into our formula, we get:

(11 + 622)/2 = 316.5

Thus, the number halfway between 11 and 622 is 316.5.

To check that our answer is correct, we subtract 11 from 316.5 and subtract 316.5 from 622 and compare the two numbers:

316.5 - 11 = 305.5
622 - 316.5 = 305.5

As you can see, the halfway number is 305.5 higher than 11 and 305.5 lower than 622. Therefore, our halfway between answer of 316.5 above is correct.
