Halfway Between 40 and 155

When you ask "What number is halfway between 40 and 155?" 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=155.

Halfway Between Line

To find the number halfway between 40 and 155, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 155 into our formula, we get:

(40 + 155)/2 = 97.5

Thus, the number halfway between 40 and 155 is 97.5.

To check that our answer is correct, we subtract 40 from 97.5 and subtract 97.5 from 155 and compare the two numbers:

97.5 - 40 = 57.5
155 - 97.5 = 57.5

As you can see, the halfway number is 57.5 higher than 40 and 57.5 lower than 155. Therefore, our halfway between answer of 97.5 above is correct.
