Halfway Between 90 and 401

When you ask "What number is halfway between 90 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=90 and Y=401.

Halfway Between Line

To find the number halfway between 90 and 401, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 401 into our formula, we get:

(90 + 401)/2 = 245.5

Thus, the number halfway between 90 and 401 is 245.5.

To check that our answer is correct, we subtract 90 from 245.5 and subtract 245.5 from 401 and compare the two numbers:

245.5 - 90 = 155.5
401 - 245.5 = 155.5

As you can see, the halfway number is 155.5 higher than 90 and 155.5 lower than 401. Therefore, our halfway between answer of 245.5 above is correct.
