Halfway Between 100 and 790

When you ask "What number is halfway between 100 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=100 and Y=790.

Halfway Between Line

To find the number halfway between 100 and 790, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 790 into our formula, we get:

(100 + 790)/2 = 445

Thus, the number halfway between 100 and 790 is 445.

To check that our answer is correct, we subtract 100 from 445 and subtract 445 from 790 and compare the two numbers:

445 - 100 = 345
790 - 445 = 345

As you can see, the halfway number is 345 higher than 100 and 345 lower than 790. Therefore, our halfway between answer of 445 above is correct.
