Halfway Between 42 and 858

When you ask "What number is halfway between 42 and 858?" 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=858.

Halfway Between Line

To find the number halfway between 42 and 858, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 858 into our formula, we get:

(42 + 858)/2 = 450

Thus, the number halfway between 42 and 858 is 450.

To check that our answer is correct, we subtract 42 from 450 and subtract 450 from 858 and compare the two numbers:

450 - 42 = 408
858 - 450 = 408

As you can see, the halfway number is 408 higher than 42 and 408 lower than 858. Therefore, our halfway between answer of 450 above is correct.
