- A. -6
- B. 6
- C. x
- D. None of these
Correct Answer: C. X
The arithmetic mean between any two numbers is simply the average of those two numbers.
In this case, the two numbers are x – 3 and x + 3.
Therefore, the arithmetic mean between x – 3 and x + 3 is:
(x – 3 + x + 3) / 2
Simplifying the equation:
2x / 2
This cancels out the 2s, leaving us with:
x
So, the arithmetic mean between x – 3 and x + 3 is simply x.
