Halfway Between 70 and 678

When you ask "What number is halfway between 70 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=70 and Y=678.

Halfway Between Line

To find the number halfway between 70 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 678 into our formula, we get:

(70 + 678)/2 = 374

Thus, the number halfway between 70 and 678 is 374.

To check that our answer is correct, we subtract 70 from 374 and subtract 374 from 678 and compare the two numbers:

374 - 70 = 304
678 - 374 = 304

As you can see, the halfway number is 304 higher than 70 and 304 lower than 678. Therefore, our halfway between answer of 374 above is correct.
