a(n) = 2·a(n-1) - 3·a(n-2) + 2·a(n-3) with a(0) = 1, a(1) = 5, a(2) = 6. A105577

a(0)=0; thereafter a(n) = a(n-1)+n if the (n-1)st digit of the sequence is even, otherwise a(n) = a(n-1)-n. A309216

The sequence is {a(n), n>=0}, the concatenation of the binary expansions of the absolute values |a(n)| is {b(n), n>=0}; start with a(0)=0; thereafter a(n) = a(n-1)+n if b(n-1)=0, otherwise a(n) = a(n-1)-n. A309217

G.f.: ∑_n>=0 (xⁿ + i)ⁿ / (1 + i·xⁿ)ⁿ⁺¹, in which the constant term is taken to be 1. A323689

a(1) = 1; a(n) = ∑_k=2..n (-1)^k * k·a(floor(n/k)). A359479
