OEIS Sequences

a(n) = n*(n+1)²/2. A6002

a(n) = n*(2·n+1)². A84367

a(n) = (p³ - p²)/2, where p = prime(n). A138416

a(n) = n² * floor(n/2). A265645

a(6n+k) = 3a(6n+k-1)-3a(6n+k-2)+2a(6n+k-3), k = 0, 1, 3, 4, 5; a(6n+2) = 3a(6n+1)-3a(6n). a(0) = a(1) = 0, a(2) = 1. A132658

Numerator of Bernoulli(n, 1/10). A158992

The lexicographically earliest sequence such that a(n) - a(n-1) is the largest proper divisor of a(n). A191614

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n) - 1, 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. A295962

"Primitive" numbers k such that k divides 4^k - 1. A323203

Sequence is identical to its third differences in absolute values: a(n+k)=3a(n+k-1)-3a(n+k-2)+2a(n+k-3), k=0, 1, 2, 3, 4, a(n+5)=3a(n+4)-3a(n+3), n > 2. A132418
