Halfway Between 5 and 289

When you ask "What number is halfway between 5 and 289?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=289.

Halfway Between Line

To find the number halfway between 5 and 289, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 289 into our formula, we get:

(5 + 289)/2 = 147

Thus, the number halfway between 5 and 289 is 147.

To check that our answer is correct, we subtract 5 from 147 and subtract 147 from 289 and compare the two numbers:

147 - 5 = 142
289 - 147 = 142

As you can see, the halfway number is 142 higher than 5 and 142 lower than 289. Therefore, our halfway between answer of 147 above is correct.
