Halfway Between 100 and 140

When you ask "What number is halfway between 100 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=100 and Y=140.

Halfway Between Line

To find the number halfway between 100 and 140, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 140 into our formula, we get:

(100 + 140)/2 = 120

Thus, the number halfway between 100 and 140 is 120.

To check that our answer is correct, we subtract 100 from 120 and subtract 120 from 140 and compare the two numbers:

120 - 100 = 20
140 - 120 = 20

As you can see, the halfway number is 20 higher than 100 and 20 lower than 140. Therefore, our halfway between answer of 120 above is correct.
