Halfway Between 77 and 158

When you ask "What number is halfway between 77 and 158?" 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=158.

Halfway Between Line

To find the number halfway between 77 and 158, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 158 into our formula, we get:

(77 + 158)/2 = 117.5

Thus, the number halfway between 77 and 158 is 117.5.

To check that our answer is correct, we subtract 77 from 117.5 and subtract 117.5 from 158 and compare the two numbers:

117.5 - 77 = 40.5
158 - 117.5 = 40.5

As you can see, the halfway number is 40.5 higher than 77 and 40.5 lower than 158. Therefore, our halfway between answer of 117.5 above is correct.
