Halfway Between 45 and 102

When you ask "What number is halfway between 45 and 102?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=102.

Halfway Between Line

To find the number halfway between 45 and 102, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 102 into our formula, we get:

(45 + 102)/2 = 73.5

Thus, the number halfway between 45 and 102 is 73.5.

To check that our answer is correct, we subtract 45 from 73.5 and subtract 73.5 from 102 and compare the two numbers:

73.5 - 45 = 28.5
102 - 73.5 = 28.5

As you can see, the halfway number is 28.5 higher than 45 and 28.5 lower than 102. Therefore, our halfway between answer of 73.5 above is correct.
