Halfway Between 100 and 154

When you ask "What number is halfway between 100 and 154?" 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=154.

Halfway Between Line

To find the number halfway between 100 and 154, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 154 into our formula, we get:

(100 + 154)/2 = 127

Thus, the number halfway between 100 and 154 is 127.

To check that our answer is correct, we subtract 100 from 127 and subtract 127 from 154 and compare the two numbers:

127 - 100 = 27
154 - 127 = 27

As you can see, the halfway number is 27 higher than 100 and 27 lower than 154. Therefore, our halfway between answer of 127 above is correct.
