Halfway Between 40 and 400

When you ask "What number is halfway between 40 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=40 and Y=400.

Halfway Between Line

To find the number halfway between 40 and 400, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 400 into our formula, we get:

(40 + 400)/2 = 220

Thus, the number halfway between 40 and 400 is 220.

To check that our answer is correct, we subtract 40 from 220 and subtract 220 from 400 and compare the two numbers:

220 - 40 = 180
400 - 220 = 180

As you can see, the halfway number is 180 higher than 40 and 180 lower than 400. Therefore, our halfway between answer of 220 above is correct.
