Halfway Between 10 and 258

When you ask "What number is halfway between 10 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=10 and Y=258.

Halfway Between Line

To find the number halfway between 10 and 258, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 258 into our formula, we get:

(10 + 258)/2 = 134

Thus, the number halfway between 10 and 258 is 134.

To check that our answer is correct, we subtract 10 from 134 and subtract 134 from 258 and compare the two numbers:

134 - 10 = 124
258 - 134 = 124

As you can see, the halfway number is 124 higher than 10 and 124 lower than 258. Therefore, our halfway between answer of 134 above is correct.
