Halfway Between 81 and 161

When you ask "What number is halfway between 81 and 161?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=81 and Y=161.

Halfway Between Line

To find the number halfway between 81 and 161, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 81 and 161 into our formula, we get:

(81 + 161)/2 = 121

Thus, the number halfway between 81 and 161 is 121.

To check that our answer is correct, we subtract 81 from 121 and subtract 121 from 161 and compare the two numbers:

121 - 81 = 40
161 - 121 = 40

As you can see, the halfway number is 40 higher than 81 and 40 lower than 161. Therefore, our halfway between answer of 121 above is correct.
