OEIS Sequences

a(n) = (n+1)*(n²+n+2)/2; g.f.: (1 + 2·x²) / (1 - x)⁴. A6000

For any number n take the polynomial formed by the product of the terms (x-π), where π's are the prime factors of n. Then calculate the area between the minimum and the maximum value of the prime factors. This sequence lists the numbers for which the area is equal to zero. A203614

a(n) = 16n² + n. A157474

The fifth term of the greedy B_n set of natural numbers. A369817

Partial sums of n 3-spaced triangular numbers beginning with t(3), e.g., a(2) = t(3)+t(6) = 6+21 = 27. A85788

Erlang C queues type triangular sequence based on A122525. A137216

Triangle T(n, k) = n^n-1 * Fibonacci(k)ⁿ⁺¹ - (n-1)! * (Fibonacci(k) - 1) * ∑_j=0..n (n·Fibonacci(k))^j/j!, with T(n, 0) = n! and T(n, 1) = n^n-1, read by rows. A137227
