Halfway Between 55 and 659

When you ask "What number is halfway between 55 and 659?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=659.

Halfway Between Line

To find the number halfway between 55 and 659, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 659 into our formula, we get:

(55 + 659)/2 = 357

Thus, the number halfway between 55 and 659 is 357.

To check that our answer is correct, we subtract 55 from 357 and subtract 357 from 659 and compare the two numbers:

357 - 55 = 302
659 - 357 = 302

As you can see, the halfway number is 302 higher than 55 and 302 lower than 659. Therefore, our halfway between answer of 357 above is correct.
