OEIS Sequences

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n), where a(0) = 3, a(1) = 4, b(0) = 1, b(1) = 2, b(2) = 5, and (a(n)) and (b(n)) are increasing complementary sequences. A295948

Number of distinct sums i³ + j³ + k³ + l³ for 0<=i<=j<=k<=l<=n. A374711

Scaled coefficients of the M. O. Rubinstein polynomials. A153359

Start with a(1)=2; thereafter the sequence is always extended by adding the n-th digit of the sequence to a(n) if a(n) is even, else subtracting it. A309529

Denominators of continued fraction convergents to sqrt(990). A42917

Start with a(1)=1; thereafter the sequence is always extended by adding the n-th digit of the sequence to a(n) if both are of the same parity, otherwise subtracting it. A309571
