Halfway Between 5 and 644

When you ask "What number is halfway between 5 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=5 and Y=644.

Halfway Between Line

To find the number halfway between 5 and 644, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 644 into our formula, we get:

(5 + 644)/2 = 324.5

Thus, the number halfway between 5 and 644 is 324.5.

To check that our answer is correct, we subtract 5 from 324.5 and subtract 324.5 from 644 and compare the two numbers:

324.5 - 5 = 319.5
644 - 324.5 = 319.5

As you can see, the halfway number is 319.5 higher than 5 and 319.5 lower than 644. Therefore, our halfway between answer of 324.5 above is correct.
