Halfway Between 55 and 397

When you ask "What number is halfway between 55 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=55 and Y=397.

Halfway Between Line

To find the number halfway between 55 and 397, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 397 into our formula, we get:

(55 + 397)/2 = 226

Thus, the number halfway between 55 and 397 is 226.

To check that our answer is correct, we subtract 55 from 226 and subtract 226 from 397 and compare the two numbers:

226 - 55 = 171
397 - 226 = 171

As you can see, the halfway number is 171 higher than 55 and 171 lower than 397. Therefore, our halfway between answer of 226 above is correct.
