Halfway Between 80 and 400

When you ask "What number is halfway between 80 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=80 and Y=400.

Halfway Between Line

To find the number halfway between 80 and 400, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 400 into our formula, we get:

(80 + 400)/2 = 240

Thus, the number halfway between 80 and 400 is 240.

To check that our answer is correct, we subtract 80 from 240 and subtract 240 from 400 and compare the two numbers:

240 - 80 = 160
400 - 240 = 160

As you can see, the halfway number is 160 higher than 80 and 160 lower than 400. Therefore, our halfway between answer of 240 above is correct.
