Halfway Between 15 and 289

When you ask "What number is halfway between 15 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=15 and Y=289.

Halfway Between Line

To find the number halfway between 15 and 289, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 289 into our formula, we get:

(15 + 289)/2 = 152

Thus, the number halfway between 15 and 289 is 152.

To check that our answer is correct, we subtract 15 from 152 and subtract 152 from 289 and compare the two numbers:

152 - 15 = 137
289 - 152 = 137

As you can see, the halfway number is 137 higher than 15 and 137 lower than 289. Therefore, our halfway between answer of 152 above is correct.
