Halfway Between 51 and 85

When you ask "What number is halfway between 51 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=51 and Y=85.

Halfway Between Line

To find the number halfway between 51 and 85, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 85 into our formula, we get:

(51 + 85)/2 = 68

Thus, the number halfway between 51 and 85 is 68.

To check that our answer is correct, we subtract 51 from 68 and subtract 68 from 85 and compare the two numbers:

68 - 51 = 17
85 - 68 = 17

As you can see, the halfway number is 17 higher than 51 and 17 lower than 85. Therefore, our halfway between answer of 68 above is correct.
