Halfway Between 85 and 429

When you ask "What number is halfway between 85 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=85 and Y=429.

Halfway Between Line

To find the number halfway between 85 and 429, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 429 into our formula, we get:

(85 + 429)/2 = 257

Thus, the number halfway between 85 and 429 is 257.

To check that our answer is correct, we subtract 85 from 257 and subtract 257 from 429 and compare the two numbers:

257 - 85 = 172
429 - 257 = 172

As you can see, the halfway number is 172 higher than 85 and 172 lower than 429. Therefore, our halfway between answer of 257 above is correct.
