1.	If an+1+bn+1an+bn represents arithmetic mean, geometric mean, harmonic mean between two distinct positive numbers a and b for n=α,β,γ respectively, then the equation whose roots are α,2β,γ is
Answer» If $\frac{a^{n + 1} + b^{n + 1}}{a^{n} + b^{n}}$ represents arithmetic mean, geometric mean, harmonic mean between two distinct positive numbers $a$ and $b$ for $n = α, β, γ$ respectively, then the equation whose roots are $α, 2 β, γ$ is
