Halfway Between 17 and 85

When you ask "What number is halfway between 17 and 85?" 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=85.

Halfway Between Line

To find the number halfway between 17 and 85, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 85 into our formula, we get:

(17 + 85)/2 = 51

Thus, the number halfway between 17 and 85 is 51.

To check that our answer is correct, we subtract 17 from 51 and subtract 51 from 85 and compare the two numbers:

51 - 17 = 34
85 - 51 = 34

As you can see, the halfway number is 34 higher than 17 and 34 lower than 85. Therefore, our halfway between answer of 51 above is correct.
