Halfway Between 77 and 425

When you ask "What number is halfway between 77 and 425?" 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=425.

Halfway Between Line

To find the number halfway between 77 and 425, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 425 into our formula, we get:

(77 + 425)/2 = 251

Thus, the number halfway between 77 and 425 is 251.

To check that our answer is correct, we subtract 77 from 251 and subtract 251 from 425 and compare the two numbers:

251 - 77 = 174
425 - 251 = 174

As you can see, the halfway number is 174 higher than 77 and 174 lower than 425. Therefore, our halfway between answer of 251 above is correct.
