Halfway Between 18 and 790

When you ask "What number is halfway between 18 and 790?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=790.

Halfway Between Line

To find the number halfway between 18 and 790, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 790 into our formula, we get:

(18 + 790)/2 = 404

Thus, the number halfway between 18 and 790 is 404.

To check that our answer is correct, we subtract 18 from 404 and subtract 404 from 790 and compare the two numbers:

404 - 18 = 386
790 - 404 = 386

As you can see, the halfway number is 386 higher than 18 and 386 lower than 790. Therefore, our halfway between answer of 404 above is correct.
