Halfway Between 100 and 342

When you ask "What number is halfway between 100 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=100 and Y=342.

Halfway Between Line

To find the number halfway between 100 and 342, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 342 into our formula, we get:

(100 + 342)/2 = 221

Thus, the number halfway between 100 and 342 is 221.

To check that our answer is correct, we subtract 100 from 221 and subtract 221 from 342 and compare the two numbers:

221 - 100 = 121
342 - 221 = 121

As you can see, the halfway number is 121 higher than 100 and 121 lower than 342. Therefore, our halfway between answer of 221 above is correct.
