Halfway Between 3 and 87

When you ask "What number is halfway between 3 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=3 and Y=87.

Halfway Between Line

To find the number halfway between 3 and 87, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 87 into our formula, we get:

(3 + 87)/2 = 45

Thus, the number halfway between 3 and 87 is 45.

To check that our answer is correct, we subtract 3 from 45 and subtract 45 from 87 and compare the two numbers:

45 - 3 = 42
87 - 45 = 42

As you can see, the halfway number is 42 higher than 3 and 42 lower than 87. Therefore, our halfway between answer of 45 above is correct.
