OEIS Sequences

Structured meta-anti-prism numbers, the n-th number from a structured n-gonal anti-prism number sequence. A100185

Sum of prime divisors of n (with repetition) is one less than the sum of prime divisors (with repetition) of n+1. A228126

a(n) = 4·a(n-1) - 3·a(n-2) - a(n-3), with a(0)=0, a(1)=0 and a(2)=1. A215404

a(n) = A(n)*7^-floor(n+1/3), where A(n) = 7·A(n-1) - 14·A(n-2) + 7·A(n-3) with A(0)=0, A(1)=1, A(2)=7. A217444

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + 2·b(n-1) - b(n-2) - 1, where a(0) = 1, a(1) = 3, b(0) = 2, b(1) = 4. A294425
