Halfway Between 42 and 510

When you ask "What number is halfway between 42 and 510?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=42 and Y=510.

Halfway Between Line

To find the number halfway between 42 and 510, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 510 into our formula, we get:

(42 + 510)/2 = 276

Thus, the number halfway between 42 and 510 is 276.

To check that our answer is correct, we subtract 42 from 276 and subtract 276 from 510 and compare the two numbers:

276 - 42 = 234
510 - 276 = 234

As you can see, the halfway number is 234 higher than 42 and 234 lower than 510. Therefore, our halfway between answer of 276 above is correct.
