Halfway Between 25 and 399

When you ask "What number is halfway between 25 and 399?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=25 and Y=399.

Halfway Between Line

To find the number halfway between 25 and 399, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 399 into our formula, we get:

(25 + 399)/2 = 212

Thus, the number halfway between 25 and 399 is 212.

To check that our answer is correct, we subtract 25 from 212 and subtract 212 from 399 and compare the two numbers:

212 - 25 = 187
399 - 212 = 187

As you can see, the halfway number is 187 higher than 25 and 187 lower than 399. Therefore, our halfway between answer of 212 above is correct.
