Halfway Between 90 and 670

When you ask "What number is halfway between 90 and 670?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=670.

Halfway Between Line

To find the number halfway between 90 and 670, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 670 into our formula, we get:

(90 + 670)/2 = 380

Thus, the number halfway between 90 and 670 is 380.

To check that our answer is correct, we subtract 90 from 380 and subtract 380 from 670 and compare the two numbers:

380 - 90 = 290
670 - 380 = 290

As you can see, the halfway number is 290 higher than 90 and 290 lower than 670. Therefore, our halfway between answer of 380 above is correct.
