Halfway Between 21 and 141

When you ask "What number is halfway between 21 and 141?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=141.

Halfway Between Line

To find the number halfway between 21 and 141, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 141 into our formula, we get:

(21 + 141)/2 = 81

Thus, the number halfway between 21 and 141 is 81.

To check that our answer is correct, we subtract 21 from 81 and subtract 81 from 141 and compare the two numbers:

81 - 21 = 60
141 - 81 = 60

As you can see, the halfway number is 60 higher than 21 and 60 lower than 141. Therefore, our halfway between answer of 81 above is correct.
