Halfway Between 45 and 121

When you ask "What number is halfway between 45 and 121?" 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=121.

Halfway Between Line

To find the number halfway between 45 and 121, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 121 into our formula, we get:

(45 + 121)/2 = 83

Thus, the number halfway between 45 and 121 is 83.

To check that our answer is correct, we subtract 45 from 83 and subtract 83 from 121 and compare the two numbers:

83 - 45 = 38
121 - 83 = 38

As you can see, the halfway number is 38 higher than 45 and 38 lower than 121. Therefore, our halfway between answer of 83 above is correct.
