Halfway Between 65 and 780

When you ask "What number is halfway between 65 and 780?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=65 and Y=780.

Halfway Between Line

To find the number halfway between 65 and 780, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 780 into our formula, we get:

(65 + 780)/2 = 422.5

Thus, the number halfway between 65 and 780 is 422.5.

To check that our answer is correct, we subtract 65 from 422.5 and subtract 422.5 from 780 and compare the two numbers:

422.5 - 65 = 357.5
780 - 422.5 = 357.5

As you can see, the halfway number is 357.5 higher than 65 and 357.5 lower than 780. Therefore, our halfway between answer of 422.5 above is correct.
