Halfway Between 51 and 104

When you ask "What number is halfway between 51 and 104?" 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=104.

Halfway Between Line

To find the number halfway between 51 and 104, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 104 into our formula, we get:

(51 + 104)/2 = 77.5

Thus, the number halfway between 51 and 104 is 77.5.

To check that our answer is correct, we subtract 51 from 77.5 and subtract 77.5 from 104 and compare the two numbers:

77.5 - 51 = 26.5
104 - 77.5 = 26.5

As you can see, the halfway number is 26.5 higher than 51 and 26.5 lower than 104. Therefore, our halfway between answer of 77.5 above is correct.
