Halfway Between 100 and 142

When you ask "What number is halfway between 100 and 142?" 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=142.

Halfway Between Line

To find the number halfway between 100 and 142, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 142 into our formula, we get:

(100 + 142)/2 = 121

Thus, the number halfway between 100 and 142 is 121.

To check that our answer is correct, we subtract 100 from 121 and subtract 121 from 142 and compare the two numbers:

121 - 100 = 21
142 - 121 = 21

As you can see, the halfway number is 21 higher than 100 and 21 lower than 142. Therefore, our halfway between answer of 121 above is correct.
