Halfway Between 99 and 429

When you ask "What number is halfway between 99 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=99 and Y=429.

Halfway Between Line

To find the number halfway between 99 and 429, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 429 into our formula, we get:

(99 + 429)/2 = 264

Thus, the number halfway between 99 and 429 is 264.

To check that our answer is correct, we subtract 99 from 264 and subtract 264 from 429 and compare the two numbers:

264 - 99 = 165
429 - 264 = 165

As you can see, the halfway number is 165 higher than 99 and 165 lower than 429. Therefore, our halfway between answer of 264 above is correct.
