Halfway Between 77 and 307

When you ask "What number is halfway between 77 and 307?" 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=307.

Halfway Between Line

To find the number halfway between 77 and 307, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 307 into our formula, we get:

(77 + 307)/2 = 192

Thus, the number halfway between 77 and 307 is 192.

To check that our answer is correct, we subtract 77 from 192 and subtract 192 from 307 and compare the two numbers:

192 - 77 = 115
307 - 192 = 115

As you can see, the halfway number is 115 higher than 77 and 115 lower than 307. Therefore, our halfway between answer of 192 above is correct.
