Halfway Between 55 and 622

When you ask "What number is halfway between 55 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=55 and Y=622.

Halfway Between Line

To find the number halfway between 55 and 622, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 622 into our formula, we get:

(55 + 622)/2 = 338.5

Thus, the number halfway between 55 and 622 is 338.5.

To check that our answer is correct, we subtract 55 from 338.5 and subtract 338.5 from 622 and compare the two numbers:

338.5 - 55 = 283.5
622 - 338.5 = 283.5

As you can see, the halfway number is 283.5 higher than 55 and 283.5 lower than 622. Therefore, our halfway between answer of 338.5 above is correct.
