Halfway Between 12 and 400

When you ask "What number is halfway between 12 and 400?" 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=400.

Halfway Between Line

To find the number halfway between 12 and 400, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 400 into our formula, we get:

(12 + 400)/2 = 206

Thus, the number halfway between 12 and 400 is 206.

To check that our answer is correct, we subtract 12 from 206 and subtract 206 from 400 and compare the two numbers:

206 - 12 = 194
400 - 206 = 194

As you can see, the halfway number is 194 higher than 12 and 194 lower than 400. Therefore, our halfway between answer of 206 above is correct.
