Halfway Between 55 and 389

When you ask "What number is halfway between 55 and 389?" 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=389.

Halfway Between Line

To find the number halfway between 55 and 389, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 389 into our formula, we get:

(55 + 389)/2 = 222

Thus, the number halfway between 55 and 389 is 222.

To check that our answer is correct, we subtract 55 from 222 and subtract 222 from 389 and compare the two numbers:

222 - 55 = 167
389 - 222 = 167

As you can see, the halfway number is 167 higher than 55 and 167 lower than 389. Therefore, our halfway between answer of 222 above is correct.
