Halfway Between 8 and 143

When you ask "What number is halfway between 8 and 143?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=143.

Halfway Between Line

To find the number halfway between 8 and 143, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 143 into our formula, we get:

(8 + 143)/2 = 75.5

Thus, the number halfway between 8 and 143 is 75.5.

To check that our answer is correct, we subtract 8 from 75.5 and subtract 75.5 from 143 and compare the two numbers:

75.5 - 8 = 67.5
143 - 75.5 = 67.5

As you can see, the halfway number is 67.5 higher than 8 and 67.5 lower than 143. Therefore, our halfway between answer of 75.5 above is correct.
