Halfway Between 4 and 151

When you ask "What number is halfway between 4 and 151?" 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=151.

Halfway Between Line

To find the number halfway between 4 and 151, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 151 into our formula, we get:

(4 + 151)/2 = 77.5

Thus, the number halfway between 4 and 151 is 77.5.

To check that our answer is correct, we subtract 4 from 77.5 and subtract 77.5 from 151 and compare the two numbers:

77.5 - 4 = 73.5
151 - 77.5 = 73.5

As you can see, the halfway number is 73.5 higher than 4 and 73.5 lower than 151. Therefore, our halfway between answer of 77.5 above is correct.
