Halfway Between 21 and 395

When you ask "What number is halfway between 21 and 395?" 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=395.

Halfway Between Line

To find the number halfway between 21 and 395, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 395 into our formula, we get:

(21 + 395)/2 = 208

Thus, the number halfway between 21 and 395 is 208.

To check that our answer is correct, we subtract 21 from 208 and subtract 208 from 395 and compare the two numbers:

208 - 21 = 187
395 - 208 = 187

As you can see, the halfway number is 187 higher than 21 and 187 lower than 395. Therefore, our halfway between answer of 208 above is correct.
