Halfway Between 64 and 690

When you ask "What number is halfway between 64 and 690?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=64 and Y=690.

Halfway Between Line

To find the number halfway between 64 and 690, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 64 and 690 into our formula, we get:

(64 + 690)/2 = 377

Thus, the number halfway between 64 and 690 is 377.

To check that our answer is correct, we subtract 64 from 377 and subtract 377 from 690 and compare the two numbers:

377 - 64 = 313
690 - 377 = 313

As you can see, the halfway number is 313 higher than 64 and 313 lower than 690. Therefore, our halfway between answer of 377 above is correct.
