I was reading the wiki On AM - GM Inequality .In it I found out that there was a proof which said that it requires a bit of combinatorics . In the last bit of the proof , it said

$$k > m_g > 0 \Rightarrow m_g \in {(0 , k)}$$

$$k \geq m_a > 0 \Rightarrow m_a \in {(0 , k]}$$.

From these how does it follow that $$m_a \geq m_g$$ ? · 1 day ago
