Halfway Between 77 and 521

When you ask "What number is halfway between 77 and 521?" 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=521.

Halfway Between Line

To find the number halfway between 77 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 521 into our formula, we get:

(77 + 521)/2 = 299

Thus, the number halfway between 77 and 521 is 299.

To check that our answer is correct, we subtract 77 from 299 and subtract 299 from 521 and compare the two numbers:

299 - 77 = 222
521 - 299 = 222

As you can see, the halfway number is 222 higher than 77 and 222 lower than 521. Therefore, our halfway between answer of 299 above is correct.
