Halfway Between 17 and 799

When you ask "What number is halfway between 17 and 799?" 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=799.

Halfway Between Line

To find the number halfway between 17 and 799, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 799 into our formula, we get:

(17 + 799)/2 = 408

Thus, the number halfway between 17 and 799 is 408.

To check that our answer is correct, we subtract 17 from 408 and subtract 408 from 799 and compare the two numbers:

408 - 17 = 391
799 - 408 = 391

As you can see, the halfway number is 391 higher than 17 and 391 lower than 799. Therefore, our halfway between answer of 408 above is correct.
