OEIS Sequences

A Collatz-Fibonacci mixture: a(1) = 1, a(2) = 2, a(n+2) = a(n+1)/2+a(n)/2 if a(n+1) and a(n) have the same parity, a(n+2) = a(n+1)+a(n) otherwise. A69202

a(n) = 3·a(n-1) + 7·a(n-2), with a(1) = 1, a(2) = 10. A137280

Good approximation to the 10ⁿ-th lower twin prime. A146310

a(1) = 1, a(n) = smallest prime number not occurring earlier such that the concatenation a(n-1) and a(n) is a composite number. A75610
