Halfway Between 4 and 51

When you ask "What number is halfway between 4 and 51?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=51.

Halfway Between Line

To find the number halfway between 4 and 51, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 51 into our formula, we get:

(4 + 51)/2 = 27.5

Thus, the number halfway between 4 and 51 is 27.5.

To check that our answer is correct, we subtract 4 from 27.5 and subtract 27.5 from 51 and compare the two numbers:

27.5 - 4 = 23.5
51 - 27.5 = 23.5

As you can see, the halfway number is 23.5 higher than 4 and 23.5 lower than 51. Therefore, our halfway between answer of 27.5 above is correct.
