Halfway Between 77 and 315

When you ask "What number is halfway between 77 and 315?" 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=315.

Halfway Between Line

To find the number halfway between 77 and 315, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 315 into our formula, we get:

(77 + 315)/2 = 196

Thus, the number halfway between 77 and 315 is 196.

To check that our answer is correct, we subtract 77 from 196 and subtract 196 from 315 and compare the two numbers:

196 - 77 = 119
315 - 196 = 119

As you can see, the halfway number is 119 higher than 77 and 119 lower than 315. Therefore, our halfway between answer of 196 above is correct.
