Halfway Between 90 and 491

When you ask "What number is halfway between 90 and 491?" 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=491.

Halfway Between Line

To find the number halfway between 90 and 491, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 491 into our formula, we get:

(90 + 491)/2 = 290.5

Thus, the number halfway between 90 and 491 is 290.5.

To check that our answer is correct, we subtract 90 from 290.5 and subtract 290.5 from 491 and compare the two numbers:

290.5 - 90 = 200.5
491 - 290.5 = 200.5

As you can see, the halfway number is 200.5 higher than 90 and 200.5 lower than 491. Therefore, our halfway between answer of 290.5 above is correct.
