The sequence of real numbers a1, a2, a3...is such that a1 = 1 and an+1=(an+1an)λ
,where λ is a constant greater than 1.
Prove by mathematical induction that for n ≥ 2,
an ≥ 2g(n) where g(n)=λn−1
Prove also that for n≥2, an+1an>2(λ−1)g(n)
This question is really confusing me. I cant even prove the base case
