Halfway Between 77 and 251

When you ask "What number is halfway between 77 and 251?" 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=251.

Halfway Between Line

To find the number halfway between 77 and 251, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 251 into our formula, we get:

(77 + 251)/2 = 164

Thus, the number halfway between 77 and 251 is 164.

To check that our answer is correct, we subtract 77 from 164 and subtract 164 from 251 and compare the two numbers:

164 - 77 = 87
251 - 164 = 87

As you can see, the halfway number is 87 higher than 77 and 87 lower than 251. Therefore, our halfway between answer of 164 above is correct.
