Halfway Between 30 and 142

When you ask "What number is halfway between 30 and 142?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=142.

Halfway Between Line

To find the number halfway between 30 and 142, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 142 into our formula, we get:

(30 + 142)/2 = 86

Thus, the number halfway between 30 and 142 is 86.

To check that our answer is correct, we subtract 30 from 86 and subtract 86 from 142 and compare the two numbers:

86 - 30 = 56
142 - 86 = 56

As you can see, the halfway number is 56 higher than 30 and 56 lower than 142. Therefore, our halfway between answer of 86 above is correct.
