Halfway Between 4 and 87

When you ask "What number is halfway between 4 and 87?" 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=87.

Halfway Between Line

To find the number halfway between 4 and 87, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 87 into our formula, we get:

(4 + 87)/2 = 45.5

Thus, the number halfway between 4 and 87 is 45.5.

To check that our answer is correct, we subtract 4 from 45.5 and subtract 45.5 from 87 and compare the two numbers:

45.5 - 4 = 41.5
87 - 45.5 = 41.5

As you can see, the halfway number is 41.5 higher than 4 and 41.5 lower than 87. Therefore, our halfway between answer of 45.5 above is correct.
