Halfway Between 90 and 408

When you ask "What number is halfway between 90 and 408?" 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=408.

Halfway Between Line

To find the number halfway between 90 and 408, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 408 into our formula, we get:

(90 + 408)/2 = 249

Thus, the number halfway between 90 and 408 is 249.

To check that our answer is correct, we subtract 90 from 249 and subtract 249 from 408 and compare the two numbers:

249 - 90 = 159
408 - 249 = 159

As you can see, the halfway number is 159 higher than 90 and 159 lower than 408. Therefore, our halfway between answer of 249 above is correct.
