Halfway Between 77 and 197

When you ask "What number is halfway between 77 and 197?" 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=197.

Halfway Between Line

To find the number halfway between 77 and 197, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 197 into our formula, we get:

(77 + 197)/2 = 137

Thus, the number halfway between 77 and 197 is 137.

To check that our answer is correct, we subtract 77 from 137 and subtract 137 from 197 and compare the two numbers:

137 - 77 = 60
197 - 137 = 60

As you can see, the halfway number is 60 higher than 77 and 60 lower than 197. Therefore, our halfway between answer of 137 above is correct.
