Halfway Between 10 and 103

When you ask "What number is halfway between 10 and 103?" 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=103.

Halfway Between Line

To find the number halfway between 10 and 103, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 103 into our formula, we get:

(10 + 103)/2 = 56.5

Thus, the number halfway between 10 and 103 is 56.5.

To check that our answer is correct, we subtract 10 from 56.5 and subtract 56.5 from 103 and compare the two numbers:

56.5 - 10 = 46.5
103 - 56.5 = 46.5

As you can see, the halfway number is 46.5 higher than 10 and 46.5 lower than 103. Therefore, our halfway between answer of 56.5 above is correct.
