Halfway Between 40 and 642

When you ask "What number is halfway between 40 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=40 and Y=642.

Halfway Between Line

To find the number halfway between 40 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 642 into our formula, we get:

(40 + 642)/2 = 341

Thus, the number halfway between 40 and 642 is 341.

To check that our answer is correct, we subtract 40 from 341 and subtract 341 from 642 and compare the two numbers:

341 - 40 = 301
642 - 341 = 301

As you can see, the halfway number is 301 higher than 40 and 301 lower than 642. Therefore, our halfway between answer of 341 above is correct.
