Halfway Between 5 and 642

When you ask "What number is halfway between 5 and 642?" 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=642.

Halfway Between Line

To find the number halfway between 5 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 642 into our formula, we get:

(5 + 642)/2 = 323.5

Thus, the number halfway between 5 and 642 is 323.5.

To check that our answer is correct, we subtract 5 from 323.5 and subtract 323.5 from 642 and compare the two numbers:

323.5 - 5 = 318.5
642 - 323.5 = 318.5

As you can see, the halfway number is 318.5 higher than 5 and 318.5 lower than 642. Therefore, our halfway between answer of 323.5 above is correct.
