Halfway Between 70 and 429

When you ask "What number is halfway between 70 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=70 and Y=429.

Halfway Between Line

To find the number halfway between 70 and 429, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 429 into our formula, we get:

(70 + 429)/2 = 249.5

Thus, the number halfway between 70 and 429 is 249.5.

To check that our answer is correct, we subtract 70 from 249.5 and subtract 249.5 from 429 and compare the two numbers:

249.5 - 70 = 179.5
429 - 249.5 = 179.5

As you can see, the halfway number is 179.5 higher than 70 and 179.5 lower than 429. Therefore, our halfway between answer of 249.5 above is correct.
