- A. (a+b)/2
- B. =_/ab
- C. 2ab/(a+b)
- D. None of these
Correct Answer: A. (a+b)/2
The arithmetic mean (A.M) between any two numbers a and b is (a+b)/2.
If we want to find a single arithmetic mean between a and b, we can set up an equation such that:
A.M = (a+b)/2
But since we are looking for a single A.M between a and b, we don’t know the exact value of the A.M. Therefore, we cannot solve for it using this equation.
However, we can make an observation that any value between a and b will be an arithmetic mean between a and b. Therefore, we can say that there are infinitely many single arithmetic means between any two numbers a and b
