Halfway Between 1 and 780

When you ask "What number is halfway between 1 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=1 and Y=780.

Halfway Between Line

To find the number halfway between 1 and 780, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 780 into our formula, we get:

(1 + 780)/2 = 390.5

Thus, the number halfway between 1 and 780 is 390.5.

To check that our answer is correct, we subtract 1 from 390.5 and subtract 390.5 from 780 and compare the two numbers:

390.5 - 1 = 389.5
780 - 390.5 = 389.5

As you can see, the halfway number is 389.5 higher than 1 and 389.5 lower than 780. Therefore, our halfway between answer of 390.5 above is correct.
