Halfway Between 15 and 790

When you ask "What number is halfway between 15 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=15 and Y=790.

Halfway Between Line

To find the number halfway between 15 and 790, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 790 into our formula, we get:

(15 + 790)/2 = 402.5

Thus, the number halfway between 15 and 790 is 402.5.

To check that our answer is correct, we subtract 15 from 402.5 and subtract 402.5 from 790 and compare the two numbers:

402.5 - 15 = 387.5
790 - 402.5 = 387.5

As you can see, the halfway number is 387.5 higher than 15 and 387.5 lower than 790. Therefore, our halfway between answer of 402.5 above is correct.
