Halfway Between 77 and 171

When you ask "What number is halfway between 77 and 171?" 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=171.

Halfway Between Line

To find the number halfway between 77 and 171, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 171 into our formula, we get:

(77 + 171)/2 = 124

Thus, the number halfway between 77 and 171 is 124.

To check that our answer is correct, we subtract 77 from 124 and subtract 124 from 171 and compare the two numbers:

124 - 77 = 47
171 - 124 = 47

As you can see, the halfway number is 47 higher than 77 and 47 lower than 171. Therefore, our halfway between answer of 124 above is correct.
