Halfway Between 64 and 77

When you ask "What number is halfway between 64 and 77?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=64 and Y=77.

Halfway Between Line

To find the number halfway between 64 and 77, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 64 and 77 into our formula, we get:

(64 + 77)/2 = 70.5

Thus, the number halfway between 64 and 77 is 70.5.

To check that our answer is correct, we subtract 64 from 70.5 and subtract 70.5 from 77 and compare the two numbers:

70.5 - 64 = 6.5
77 - 70.5 = 6.5

As you can see, the halfway number is 6.5 higher than 64 and 6.5 lower than 77. Therefore, our halfway between answer of 70.5 above is correct.
