Halfway Between 11 and 649

When you ask "What number is halfway between 11 and 649?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=649.

Halfway Between Line

To find the number halfway between 11 and 649, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 649 into our formula, we get:

(11 + 649)/2 = 330

Thus, the number halfway between 11 and 649 is 330.

To check that our answer is correct, we subtract 11 from 330 and subtract 330 from 649 and compare the two numbers:

330 - 11 = 319
649 - 330 = 319

As you can see, the halfway number is 319 higher than 11 and 319 lower than 649. Therefore, our halfway between answer of 330 above is correct.
