Halfway Between 18 and 342

When you ask "What number is halfway between 18 and 342?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=342.

Halfway Between Line

To find the number halfway between 18 and 342, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 342 into our formula, we get:

(18 + 342)/2 = 180

Thus, the number halfway between 18 and 342 is 180.

To check that our answer is correct, we subtract 18 from 180 and subtract 180 from 342 and compare the two numbers:

180 - 18 = 162
342 - 180 = 162

As you can see, the halfway number is 162 higher than 18 and 162 lower than 342. Therefore, our halfway between answer of 180 above is correct.
