Halfway Between 40 and 258

When you ask "What number is halfway between 40 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=40 and Y=258.

Halfway Between Line

To find the number halfway between 40 and 258, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 258 into our formula, we get:

(40 + 258)/2 = 149

Thus, the number halfway between 40 and 258 is 149.

To check that our answer is correct, we subtract 40 from 149 and subtract 149 from 258 and compare the two numbers:

149 - 40 = 109
258 - 149 = 109

As you can see, the halfway number is 109 higher than 40 and 109 lower than 258. Therefore, our halfway between answer of 149 above is correct.
