Halfway Between 77 and 312

When you ask "What number is halfway between 77 and 312?" 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=312.

Halfway Between Line

To find the number halfway between 77 and 312, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 312 into our formula, we get:

(77 + 312)/2 = 194.5

Thus, the number halfway between 77 and 312 is 194.5.

To check that our answer is correct, we subtract 77 from 194.5 and subtract 194.5 from 312 and compare the two numbers:

194.5 - 77 = 117.5
312 - 194.5 = 117.5

As you can see, the halfway number is 117.5 higher than 77 and 117.5 lower than 312. Therefore, our halfway between answer of 194.5 above is correct.
