Halfway Between 77 and 285

When you ask "What number is halfway between 77 and 285?" 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=285.

Halfway Between Line

To find the number halfway between 77 and 285, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 285 into our formula, we get:

(77 + 285)/2 = 181

Thus, the number halfway between 77 and 285 is 181.

To check that our answer is correct, we subtract 77 from 181 and subtract 181 from 285 and compare the two numbers:

181 - 77 = 104
285 - 181 = 104

As you can see, the halfway number is 104 higher than 77 and 104 lower than 285. Therefore, our halfway between answer of 181 above is correct.
