发帖数: 14468 | 8 See:
1. Two real numbers a and b are not equal.
2. Take the mathematical mean (a+b)/2 (m_1); take the geometric mean sqrt(ab
)(g_1).
3. Take the mathematical mean of m_1 and g_1 (m_2); take the geometric mean
of m_1 and g_1 (g_2).
4. Take the mathematical mean of m_2 and g_2 (m_3); ......
Question: does the difference between m_k and g_k converge as k approaches
infinity?

As k increases, the difference becomes smaller. Just wonder if it converges
to zero. Is this a valid question?

发帖数: 14468 | 12 That is a good point. Anyway, you know what I want to ask.
Suppose a and b are both positive.
