Sep16 accepted square root of $1/2 + \sqrt3/2?$ Sep16 comment square root of $1/2 + \sqrt3/2?$ Thanks, though my question was not about rational coefficients specifically. I was more concerned about the validity of my therefore, for which your answer is useful. Sep16 awarded Supporter Sep16 comment square root of $1/2 + \sqrt3/2?$ Thanks. My question was not particularly about rational coefficient, but the consideration is interesting. Sep15 asked square root of $1/2 + \sqrt3/2?$ Sep11 comment closed form for $d(4)=2$, $d(n+1)=d(n)+n-1$? thanks for this insight. Sep11 awarded Editor Sep11 revised closed form for $d(4)=2$, $d(n+1)=d(n)+n-1$? edited body Sep11 comment closed form for $d(4)=2$, $d(n+1)=d(n)+n-1$? Yes sorry, English is my 2nd language. I edited the question Sep11 comment closed form for $d(4)=2$, $d(n+1)=d(n)+n-1$? Thanks, I need to get more familiar with this telescoping idea.
