Halfway Between 20 and 378

When you ask "What number is halfway between 20 and 378?" 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=378.

Halfway Between Line

To find the number halfway between 20 and 378, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 378 into our formula, we get:

(20 + 378)/2 = 199

Thus, the number halfway between 20 and 378 is 199.

To check that our answer is correct, we subtract 20 from 199 and subtract 199 from 378 and compare the two numbers:

199 - 20 = 179
378 - 199 = 179

As you can see, the halfway number is 179 higher than 20 and 179 lower than 378. Therefore, our halfway between answer of 199 above is correct.
