Halfway Between 1 and 154

When you ask "What number is halfway between 1 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=1 and Y=154.

Halfway Between Line

To find the number halfway between 1 and 154, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 154 into our formula, we get:

(1 + 154)/2 = 77.5

Thus, the number halfway between 1 and 154 is 77.5.

To check that our answer is correct, we subtract 1 from 77.5 and subtract 77.5 from 154 and compare the two numbers:

77.5 - 1 = 76.5
154 - 77.5 = 76.5

As you can see, the halfway number is 76.5 higher than 1 and 76.5 lower than 154. Therefore, our halfway between answer of 77.5 above is correct.
