Halfway Between 40 and 128

When you ask "What number is halfway between 40 and 128?" 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=128.

Halfway Between Line

To find the number halfway between 40 and 128, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 128 into our formula, we get:

(40 + 128)/2 = 84

Thus, the number halfway between 40 and 128 is 84.

To check that our answer is correct, we subtract 40 from 84 and subtract 84 from 128 and compare the two numbers:

84 - 40 = 44
128 - 84 = 44

As you can see, the halfway number is 44 higher than 40 and 44 lower than 128. Therefore, our halfway between answer of 84 above is correct.
