Halfway Between 90 and 258

When you ask "What number is halfway between 90 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=90 and Y=258.

Halfway Between Line

To find the number halfway between 90 and 258, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 258 into our formula, we get:

(90 + 258)/2 = 174

Thus, the number halfway between 90 and 258 is 174.

To check that our answer is correct, we subtract 90 from 174 and subtract 174 from 258 and compare the two numbers:

174 - 90 = 84
258 - 174 = 84

As you can see, the halfway number is 84 higher than 90 and 84 lower than 258. Therefore, our halfway between answer of 174 above is correct.
