Halfway Between 66 and 429

When you ask "What number is halfway between 66 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=66 and Y=429.

Halfway Between Line

To find the number halfway between 66 and 429, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 429 into our formula, we get:

(66 + 429)/2 = 247.5

Thus, the number halfway between 66 and 429 is 247.5.

To check that our answer is correct, we subtract 66 from 247.5 and subtract 247.5 from 429 and compare the two numbers:

247.5 - 66 = 181.5
429 - 247.5 = 181.5

As you can see, the halfway number is 181.5 higher than 66 and 181.5 lower than 429. Therefore, our halfway between answer of 247.5 above is correct.
