Halfway Between 55 and 387

When you ask "What number is halfway between 55 and 387?" 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=387.

Halfway Between Line

To find the number halfway between 55 and 387, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 387 into our formula, we get:

(55 + 387)/2 = 221

Thus, the number halfway between 55 and 387 is 221.

To check that our answer is correct, we subtract 55 from 221 and subtract 221 from 387 and compare the two numbers:

221 - 55 = 166
387 - 221 = 166

As you can see, the halfway number is 166 higher than 55 and 166 lower than 387. Therefore, our halfway between answer of 221 above is correct.
