Halfway Between 42 and 290

When you ask "What number is halfway between 42 and 290?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=42 and Y=290.

Halfway Between Line

To find the number halfway between 42 and 290, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 290 into our formula, we get:

(42 + 290)/2 = 166

Thus, the number halfway between 42 and 290 is 166.

To check that our answer is correct, we subtract 42 from 166 and subtract 166 from 290 and compare the two numbers:

166 - 42 = 124
290 - 166 = 124

As you can see, the halfway number is 124 higher than 42 and 124 lower than 290. Therefore, our halfway between answer of 166 above is correct.
