Halfway Between 40 and 644

When you ask "What number is halfway between 40 and 644?" 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=644.

Halfway Between Line

To find the number halfway between 40 and 644, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 644 into our formula, we get:

(40 + 644)/2 = 342

Thus, the number halfway between 40 and 644 is 342.

To check that our answer is correct, we subtract 40 from 342 and subtract 342 from 644 and compare the two numbers:

342 - 40 = 302
644 - 342 = 302

As you can see, the halfway number is 302 higher than 40 and 302 lower than 644. Therefore, our halfway between answer of 342 above is correct.
