Halfway Between 21 and 377

When you ask "What number is halfway between 21 and 377?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=377.

Halfway Between Line

To find the number halfway between 21 and 377, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 377 into our formula, we get:

(21 + 377)/2 = 199

Thus, the number halfway between 21 and 377 is 199.

To check that our answer is correct, we subtract 21 from 199 and subtract 199 from 377 and compare the two numbers:

199 - 21 = 178
377 - 199 = 178

As you can see, the halfway number is 178 higher than 21 and 178 lower than 377. Therefore, our halfway between answer of 199 above is correct.
