Halfway Between 77 and 92

When you ask "What number is halfway between 77 and 92?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=77 and Y=92.

Halfway Between Line

To find the number halfway between 77 and 92, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 92 into our formula, we get:

(77 + 92)/2 = 84.5

Thus, the number halfway between 77 and 92 is 84.5.

To check that our answer is correct, we subtract 77 from 84.5 and subtract 84.5 from 92 and compare the two numbers:

84.5 - 77 = 7.5
92 - 84.5 = 7.5

As you can see, the halfway number is 7.5 higher than 77 and 7.5 lower than 92. Therefore, our halfway between answer of 84.5 above is correct.
