a(n) = Fibonacci(n)*2ⁿ + 1. A6483

Define C(n) by the recursion C(0) = 4·i where i² = -1, C(n+1) = 1/(1 + C(n)), then a(n) = 4*(-1)ⁿ/Im(C(n)) where Im(z) denotes the imaginary part of z. A69961

a(n) = T(n,n), array T given by A048472. A48482

Least k such that k·10ⁿ-9, k·10ⁿ-7, k·10ⁿ-3 and k·10ⁿ-1 are all prime. A64432

a(n) = T(4,n), array T given by A048472. A48476

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n-2) + 2, where a(0) = 1, a(1) = 2, b(0) = 3. A294534
