OEIS Sequences

a(n) = n³ + 2. A84380

a(n) = ∑_d∣n sigma₃(d). A321140

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n-1) + 2·b(n-2), where a(0) = 1, a(1) = 2, b(0) = 3, and (a(n)) and (b(n)) are increasing complementary sequences. A294559

Semiprimes of the form n³ + 2. A259189

a(n) = smallest M such that M is not divisible by prime(1), ..., prime(n), but is divisible by ∑_i=1..n (M mod prime(i)); or 0 if no such M exists. A106572
