SUMMARY

The discussion focuses on proving that F_n divides F_{kn} using mathematical induction. The user successfully established the base case with F_1 dividing F_k, where F_1 equals 1. The inductive step involves showing that if F_n divides F_{kn}, then F_{n+1} divides F_{kn+k}. The relationship F_{kn+k} = F_kF_{kn+1} + F_{k-1}F_{kn} is utilized to further the proof.

Homework Statement


I have proved the first one and I am trying to do the second using the result from part 1)


Homework Equations



F_1=1, F_2=2, F_n=F_{n-1}+F_{n-2}

The Attempt at a Solution


base case: F_1|F_k sinceF_1=1

Assume it works for n, F_n|F_{kn}
show F_{n+1}|F_{kn+k}

Well, using the part 1)
F_{kn+k}=F_kF_{kn+1}+F_{k-1}F_{kn}

That's as far as i could go..
