However, I have a few questions: for the first question, how could the sums of $Q$ be smaller than those of $P$, when we have already assumed that $Q\supseteq P$? And for the second question, would taking the sequence $P_1=[a,b]$, $P_2=[a,\frac{a+b}{2},b]$, $P_3=[a,\frac{3a+b}{4},\frac{a+b}{2},\frac{a+3b}{4},b]$, $\dots$ be a good start?

I understand now. :) Thanks, guys! Apr 25 comment If $m$ and $n$ are positive integers, then $(F_m,F_n)=F_{(m,n)}$. There's a step where he states that $(f_{n-m},f_m)=f_{(n-m,m)}$. Is that something that's well-known?

Apr 25 comment Showing that $f_{2n+1}=f_{n+1}^2+f_n^2$. I like this approach a lot. Thanks! Apr 25 accepted Showing that $f_{2n+1}=f_{n+1}^2+f_n^2$. Apr 25 comment Showing that $f_{2n+1}=f_{n+1}^2+f_n^2$. How did you obtain that? Did you know it beforehand?
