Halfway Between 15 and 75

When you ask "What number is halfway between 15 and 75?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=75.

Halfway Between Line

To find the number halfway between 15 and 75, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 75 into our formula, we get:

(15 + 75)/2 = 45

Thus, the number halfway between 15 and 75 is 45.

To check that our answer is correct, we subtract 15 from 45 and subtract 45 from 75 and compare the two numbers:

45 - 15 = 30
75 - 45 = 30

As you can see, the halfway number is 30 higher than 15 and 30 lower than 75. Therefore, our halfway between answer of 45 above is correct.
