Halfway Between 90 and 637

When you ask "What number is halfway between 90 and 637?" 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=637.

Halfway Between Line

To find the number halfway between 90 and 637, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 637 into our formula, we get:

(90 + 637)/2 = 363.5

Thus, the number halfway between 90 and 637 is 363.5.

To check that our answer is correct, we subtract 90 from 363.5 and subtract 363.5 from 637 and compare the two numbers:

363.5 - 90 = 273.5
637 - 363.5 = 273.5

As you can see, the halfway number is 273.5 higher than 90 and 273.5 lower than 637. Therefore, our halfway between answer of 363.5 above is correct.
