Halfway Between 40 and 657

When you ask "What number is halfway between 40 and 657?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=657.

Halfway Between Line

To find the number halfway between 40 and 657, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 657 into our formula, we get:

(40 + 657)/2 = 348.5

Thus, the number halfway between 40 and 657 is 348.5.

To check that our answer is correct, we subtract 40 from 348.5 and subtract 348.5 from 657 and compare the two numbers:

348.5 - 40 = 308.5
657 - 348.5 = 308.5

As you can see, the halfway number is 308.5 higher than 40 and 308.5 lower than 657. Therefore, our halfway between answer of 348.5 above is correct.
