Halfway Between 7 and 154

When you ask "What number is halfway between 7 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=7 and Y=154.

Halfway Between Line

To find the number halfway between 7 and 154, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 7 and 154 into our formula, we get:

(7 + 154)/2 = 80.5

Thus, the number halfway between 7 and 154 is 80.5.

To check that our answer is correct, we subtract 7 from 80.5 and subtract 80.5 from 154 and compare the two numbers:

80.5 - 7 = 73.5
154 - 80.5 = 73.5

As you can see, the halfway number is 73.5 higher than 7 and 73.5 lower than 154. Therefore, our halfway between answer of 80.5 above is correct.
