Halfway Between 9 and 142

When you ask "What number is halfway between 9 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=9 and Y=142.

Halfway Between Line

To find the number halfway between 9 and 142, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 142 into our formula, we get:

(9 + 142)/2 = 75.5

Thus, the number halfway between 9 and 142 is 75.5.

To check that our answer is correct, we subtract 9 from 75.5 and subtract 75.5 from 142 and compare the two numbers:

75.5 - 9 = 66.5
142 - 75.5 = 66.5

As you can see, the halfway number is 66.5 higher than 9 and 66.5 lower than 142. Therefore, our halfway between answer of 75.5 above is correct.
