Halfway Between 77 and 790

When you ask "What number is halfway between 77 and 790?" 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=790.

Halfway Between Line

To find the number halfway between 77 and 790, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 790 into our formula, we get:

(77 + 790)/2 = 433.5

Thus, the number halfway between 77 and 790 is 433.5.

To check that our answer is correct, we subtract 77 from 433.5 and subtract 433.5 from 790 and compare the two numbers:

433.5 - 77 = 356.5
790 - 433.5 = 356.5

As you can see, the halfway number is 356.5 higher than 77 and 356.5 lower than 790. Therefore, our halfway between answer of 433.5 above is correct.
