Halfway Between 4 and 258

When you ask "What number is halfway between 4 and 258?" 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=258.

Halfway Between Line

To find the number halfway between 4 and 258, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 258 into our formula, we get:

(4 + 258)/2 = 131

Thus, the number halfway between 4 and 258 is 131.

To check that our answer is correct, we subtract 4 from 131 and subtract 131 from 258 and compare the two numbers:

131 - 4 = 127
258 - 131 = 127

As you can see, the halfway number is 127 higher than 4 and 127 lower than 258. Therefore, our halfway between answer of 131 above is correct.
