Halfway Between 77 and 670

When you ask "What number is halfway between 77 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=77 and Y=670.

Halfway Between Line

To find the number halfway between 77 and 670, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 670 into our formula, we get:

(77 + 670)/2 = 373.5

Thus, the number halfway between 77 and 670 is 373.5.

To check that our answer is correct, we subtract 77 from 373.5 and subtract 373.5 from 670 and compare the two numbers:

373.5 - 77 = 296.5
670 - 373.5 = 296.5

As you can see, the halfway number is 296.5 higher than 77 and 296.5 lower than 670. Therefore, our halfway between answer of 373.5 above is correct.
