Halfway Between 15 and 140

When you ask "What number is halfway between 15 and 140?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=140.

Halfway Between Line

To find the number halfway between 15 and 140, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 140 into our formula, we get:

(15 + 140)/2 = 77.5

Thus, the number halfway between 15 and 140 is 77.5.

To check that our answer is correct, we subtract 15 from 77.5 and subtract 77.5 from 140 and compare the two numbers:

77.5 - 15 = 62.5
140 - 77.5 = 62.5

As you can see, the halfway number is 62.5 higher than 15 and 62.5 lower than 140. Therefore, our halfway between answer of 77.5 above is correct.
