Halfway Between 40 and 637

When you ask "What number is halfway between 40 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=40 and Y=637.

Halfway Between Line

To find the number halfway between 40 and 637, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 637 into our formula, we get:

(40 + 637)/2 = 338.5

Thus, the number halfway between 40 and 637 is 338.5.

To check that our answer is correct, we subtract 40 from 338.5 and subtract 338.5 from 637 and compare the two numbers:

338.5 - 40 = 298.5
637 - 338.5 = 298.5

As you can see, the halfway number is 298.5 higher than 40 and 298.5 lower than 637. Therefore, our halfway between answer of 338.5 above is correct.
