Halfway Between 43 and 665

When you ask "What number is halfway between 43 and 665?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=43 and Y=665.

Halfway Between Line

To find the number halfway between 43 and 665, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 665 into our formula, we get:

(43 + 665)/2 = 354

Thus, the number halfway between 43 and 665 is 354.

To check that our answer is correct, we subtract 43 from 354 and subtract 354 from 665 and compare the two numbers:

354 - 43 = 311
665 - 354 = 311

As you can see, the halfway number is 311 higher than 43 and 311 lower than 665. Therefore, our halfway between answer of 354 above is correct.
