Halfway Between 4 and 150

When you ask "What number is halfway between 4 and 150?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=150.

Halfway Between Line

To find the number halfway between 4 and 150, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 150 into our formula, we get:

(4 + 150)/2 = 77

Thus, the number halfway between 4 and 150 is 77.

To check that our answer is correct, we subtract 4 from 77 and subtract 77 from 150 and compare the two numbers:

77 - 4 = 73
150 - 77 = 73

As you can see, the halfway number is 73 higher than 4 and 73 lower than 150. Therefore, our halfway between answer of 77 above is correct.
