Halfway Between 40 and 159

When you ask "What number is halfway between 40 and 159?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=159.

Halfway Between Line

To find the number halfway between 40 and 159, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 159 into our formula, we get:

(40 + 159)/2 = 99.5

Thus, the number halfway between 40 and 159 is 99.5.

To check that our answer is correct, we subtract 40 from 99.5 and subtract 99.5 from 159 and compare the two numbers:

99.5 - 40 = 59.5
159 - 99.5 = 59.5

As you can see, the halfway number is 59.5 higher than 40 and 59.5 lower than 159. Therefore, our halfway between answer of 99.5 above is correct.
