OEIS Sequences

Let u(1) = x and u(n+1) = (n²/u(n)) + 1 for n >= 1; then a(n) is such that u(n) = (b(n)*x + c(n))/(d(n)*x + a(n)) (in lowest terms) and a(n), b(n), c(n), d(n) are positive integers. A75829

Let u(1) = x and u(n+1) = (n²/u(n)) + 1 for n >= 1; then a(n) is such that u(n) =(b(n)*x + a(n))/(c(n)*x + d(n)) (in lowest terms) and a(n), b(n), c(n), d(n) are positive integers. A75828

a(n) is the difference between denominator and numerator of the n-th alternating harmonic number ∑_k=1..n (-1)^k+1/k = A058313(n)/A058312(n). A119248

a(n) is the number of times we must iterate A097246, starting at n, before the result is squarefree. A97249
