Halfway Between 15 and 291

When you ask "What number is halfway between 15 and 291?" 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=291.

Halfway Between Line

To find the number halfway between 15 and 291, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 291 into our formula, we get:

(15 + 291)/2 = 153

Thus, the number halfway between 15 and 291 is 153.

To check that our answer is correct, we subtract 15 from 153 and subtract 153 from 291 and compare the two numbers:

153 - 15 = 138
291 - 153 = 138

As you can see, the halfway number is 138 higher than 15 and 138 lower than 291. Therefore, our halfway between answer of 153 above is correct.
