Halfway Between 45 and 84

When you ask "What number is halfway between 45 and 84?" 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=84.

Halfway Between Line

To find the number halfway between 45 and 84, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 84 into our formula, we get:

(45 + 84)/2 = 64.5

Thus, the number halfway between 45 and 84 is 64.5.

To check that our answer is correct, we subtract 45 from 64.5 and subtract 64.5 from 84 and compare the two numbers:

64.5 - 45 = 19.5
84 - 64.5 = 19.5

As you can see, the halfway number is 19.5 higher than 45 and 19.5 lower than 84. Therefore, our halfway between answer of 64.5 above is correct.
