Halfway Between 79 and 521

When you ask "What number is halfway between 79 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=79 and Y=521.

Halfway Between Line

To find the number halfway between 79 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 79 and 521 into our formula, we get:

(79 + 521)/2 = 300

Thus, the number halfway between 79 and 521 is 300.

To check that our answer is correct, we subtract 79 from 300 and subtract 300 from 521 and compare the two numbers:

300 - 79 = 221
521 - 300 = 221

As you can see, the halfway number is 221 higher than 79 and 221 lower than 521. Therefore, our halfway between answer of 300 above is correct.
