Halfway Between 70 and 491

When you ask "What number is halfway between 70 and 491?" 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=491.

Halfway Between Line

To find the number halfway between 70 and 491, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 491 into our formula, we get:

(70 + 491)/2 = 280.5

Thus, the number halfway between 70 and 491 is 280.5.

To check that our answer is correct, we subtract 70 from 280.5 and subtract 280.5 from 491 and compare the two numbers:

280.5 - 70 = 210.5
491 - 280.5 = 210.5

As you can see, the halfway number is 210.5 higher than 70 and 210.5 lower than 491. Therefore, our halfway between answer of 280.5 above is correct.
