Halfway Between 89 and 429

When you ask "What number is halfway between 89 and 429?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=429.

Halfway Between Line

To find the number halfway between 89 and 429, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 429 into our formula, we get:

(89 + 429)/2 = 259

Thus, the number halfway between 89 and 429 is 259.

To check that our answer is correct, we subtract 89 from 259 and subtract 259 from 429 and compare the two numbers:

259 - 89 = 170
429 - 259 = 170

As you can see, the halfway number is 170 higher than 89 and 170 lower than 429. Therefore, our halfway between answer of 259 above is correct.
