Halfway Between 18 and 58

When you ask "What number is halfway between 18 and 58?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=58.

Halfway Between Line

To find the number halfway between 18 and 58, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 58 into our formula, we get:

(18 + 58)/2 = 38

Thus, the number halfway between 18 and 58 is 38.

To check that our answer is correct, we subtract 18 from 38 and subtract 38 from 58 and compare the two numbers:

38 - 18 = 20
58 - 38 = 20

As you can see, the halfway number is 20 higher than 18 and 20 lower than 58. Therefore, our halfway between answer of 38 above is correct.
