Halfway Between 20 and 381

When you ask "What number is halfway between 20 and 381?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=381.

Halfway Between Line

To find the number halfway between 20 and 381, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 381 into our formula, we get:

(20 + 381)/2 = 200.5

Thus, the number halfway between 20 and 381 is 200.5.

To check that our answer is correct, we subtract 20 from 200.5 and subtract 200.5 from 381 and compare the two numbers:

200.5 - 20 = 180.5
381 - 200.5 = 180.5

As you can see, the halfway number is 180.5 higher than 20 and 180.5 lower than 381. Therefore, our halfway between answer of 200.5 above is correct.
