Halfway Between 21 and 385

When you ask "What number is halfway between 21 and 385?" 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=385.

Halfway Between Line

To find the number halfway between 21 and 385, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 385 into our formula, we get:

(21 + 385)/2 = 203

Thus, the number halfway between 21 and 385 is 203.

To check that our answer is correct, we subtract 21 from 203 and subtract 203 from 385 and compare the two numbers:

203 - 21 = 182
385 - 203 = 182

As you can see, the halfway number is 182 higher than 21 and 182 lower than 385. Therefore, our halfway between answer of 203 above is correct.
