Halfway Between 42 and 870

When you ask "What number is halfway between 42 and 870?" 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=870.

Halfway Between Line

To find the number halfway between 42 and 870, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 870 into our formula, we get:

(42 + 870)/2 = 456

Thus, the number halfway between 42 and 870 is 456.

To check that our answer is correct, we subtract 42 from 456 and subtract 456 from 870 and compare the two numbers:

456 - 42 = 414
870 - 456 = 414

As you can see, the halfway number is 414 higher than 42 and 414 lower than 870. Therefore, our halfway between answer of 456 above is correct.
