Halfway Between 15 and 429

When you ask "What number is halfway between 15 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=15 and Y=429.

Halfway Between Line

To find the number halfway between 15 and 429, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 429 into our formula, we get:

(15 + 429)/2 = 222

Thus, the number halfway between 15 and 429 is 222.

To check that our answer is correct, we subtract 15 from 222 and subtract 222 from 429 and compare the two numbers:

222 - 15 = 207
429 - 222 = 207

As you can see, the halfway number is 207 higher than 15 and 207 lower than 429. Therefore, our halfway between answer of 222 above is correct.
