Halfway Between 45 and 400

When you ask "What number is halfway between 45 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=45 and Y=400.

Halfway Between Line

To find the number halfway between 45 and 400, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 400 into our formula, we get:

(45 + 400)/2 = 222.5

Thus, the number halfway between 45 and 400 is 222.5.

To check that our answer is correct, we subtract 45 from 222.5 and subtract 222.5 from 400 and compare the two numbers:

222.5 - 45 = 177.5
400 - 222.5 = 177.5

As you can see, the halfway number is 177.5 higher than 45 and 177.5 lower than 400. Therefore, our halfway between answer of 222.5 above is correct.
