Halfway Between 10 and 45

When you ask "What number is halfway between 10 and 45?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=10 and Y=45.

Halfway Between Line

To find the number halfway between 10 and 45, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 45 into our formula, we get:

(10 + 45)/2 = 27.5

Thus, the number halfway between 10 and 45 is 27.5.

To check that our answer is correct, we subtract 10 from 27.5 and subtract 27.5 from 45 and compare the two numbers:

27.5 - 10 = 17.5
45 - 27.5 = 17.5

As you can see, the halfway number is 17.5 higher than 10 and 17.5 lower than 45. Therefore, our halfway between answer of 27.5 above is correct.
