Halfway Between 45 and 397

When you ask "What number is halfway between 45 and 397?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=397.

Halfway Between Line

To find the number halfway between 45 and 397, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 397 into our formula, we get:

(45 + 397)/2 = 221

Thus, the number halfway between 45 and 397 is 221.

To check that our answer is correct, we subtract 45 from 221 and subtract 221 from 397 and compare the two numbers:

221 - 45 = 176
397 - 221 = 176

As you can see, the halfway number is 176 higher than 45 and 176 lower than 397. Therefore, our halfway between answer of 221 above is correct.
