Halfway Between 17 and 798

When you ask "What number is halfway between 17 and 798?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=17 and Y=798.

Halfway Between Line

To find the number halfway between 17 and 798, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 798 into our formula, we get:

(17 + 798)/2 = 407.5

Thus, the number halfway between 17 and 798 is 407.5.

To check that our answer is correct, we subtract 17 from 407.5 and subtract 407.5 from 798 and compare the two numbers:

407.5 - 17 = 390.5
798 - 407.5 = 390.5

As you can see, the halfway number is 390.5 higher than 17 and 390.5 lower than 798. Therefore, our halfway between answer of 407.5 above is correct.
