Halfway Between 12 and 401

When you ask "What number is halfway between 12 and 401?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=401.

Halfway Between Line

To find the number halfway between 12 and 401, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 401 into our formula, we get:

(12 + 401)/2 = 206.5

Thus, the number halfway between 12 and 401 is 206.5.

To check that our answer is correct, we subtract 12 from 206.5 and subtract 206.5 from 401 and compare the two numbers:

206.5 - 12 = 194.5
401 - 206.5 = 194.5

As you can see, the halfway number is 194.5 higher than 12 and 194.5 lower than 401. Therefore, our halfway between answer of 206.5 above is correct.
