Halfway Between 64 and 678

When you ask "What number is halfway between 64 and 678?" 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=678.

Halfway Between Line

To find the number halfway between 64 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 64 and 678 into our formula, we get:

(64 + 678)/2 = 371

Thus, the number halfway between 64 and 678 is 371.

To check that our answer is correct, we subtract 64 from 371 and subtract 371 from 678 and compare the two numbers:

371 - 64 = 307
678 - 371 = 307

As you can see, the halfway number is 307 higher than 64 and 307 lower than 678. Therefore, our halfway between answer of 371 above is correct.
