Halfway Between 4 and 290

When you ask "What number is halfway between 4 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=4 and Y=290.

Halfway Between Line

To find the number halfway between 4 and 290, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 290 into our formula, we get:

(4 + 290)/2 = 147

Thus, the number halfway between 4 and 290 is 147.

To check that our answer is correct, we subtract 4 from 147 and subtract 147 from 290 and compare the two numbers:

147 - 4 = 143
290 - 147 = 143

As you can see, the halfway number is 143 higher than 4 and 143 lower than 290. Therefore, our halfway between answer of 147 above is correct.
