Halfway Between 42 and 658

When you ask "What number is halfway between 42 and 658?" 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=658.

Halfway Between Line

To find the number halfway between 42 and 658, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 658 into our formula, we get:

(42 + 658)/2 = 350

Thus, the number halfway between 42 and 658 is 350.

To check that our answer is correct, we subtract 42 from 350 and subtract 350 from 658 and compare the two numbers:

350 - 42 = 308
658 - 350 = 308

As you can see, the halfway number is 308 higher than 42 and 308 lower than 658. Therefore, our halfway between answer of 350 above is correct.
