Halfway Between 45 and 342

When you ask "What number is halfway between 45 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=45 and Y=342.

Halfway Between Line

To find the number halfway between 45 and 342, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 342 into our formula, we get:

(45 + 342)/2 = 193.5

Thus, the number halfway between 45 and 342 is 193.5.

To check that our answer is correct, we subtract 45 from 193.5 and subtract 193.5 from 342 and compare the two numbers:

193.5 - 45 = 148.5
342 - 193.5 = 148.5

As you can see, the halfway number is 148.5 higher than 45 and 148.5 lower than 342. Therefore, our halfway between answer of 193.5 above is correct.
