Halfway Between 20 and 345

When you ask "What number is halfway between 20 and 345?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=345.

Halfway Between Line

To find the number halfway between 20 and 345, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 345 into our formula, we get:

(20 + 345)/2 = 182.5

Thus, the number halfway between 20 and 345 is 182.5.

To check that our answer is correct, we subtract 20 from 182.5 and subtract 182.5 from 345 and compare the two numbers:

182.5 - 20 = 162.5
345 - 182.5 = 162.5

As you can see, the halfway number is 162.5 higher than 20 and 162.5 lower than 345. Therefore, our halfway between answer of 182.5 above is correct.
