Halfway Between 18 and 662

When you ask "What number is halfway between 18 and 662?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=662.

Halfway Between Line

To find the number halfway between 18 and 662, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 662 into our formula, we get:

(18 + 662)/2 = 340

Thus, the number halfway between 18 and 662 is 340.

To check that our answer is correct, we subtract 18 from 340 and subtract 340 from 662 and compare the two numbers:

340 - 18 = 322
662 - 340 = 322

As you can see, the halfway number is 322 higher than 18 and 322 lower than 662. Therefore, our halfway between answer of 340 above is correct.
