Halfway Between 80 and 658

When you ask "What number is halfway between 80 and 658?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=658.

Halfway Between Line

To find the number halfway between 80 and 658, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 658 into our formula, we get:

(80 + 658)/2 = 369

Thus, the number halfway between 80 and 658 is 369.

To check that our answer is correct, we subtract 80 from 369 and subtract 369 from 658 and compare the two numbers:

369 - 80 = 289
658 - 369 = 289

As you can see, the halfway number is 289 higher than 80 and 289 lower than 658. Therefore, our halfway between answer of 369 above is correct.
