OEIS Sequences

a(n) = 2ⁿ * ∑_k=0..n k^p*q^k, where p=2, q=-1/2. A232603

An oscillating sequence: a(n) = n² + 2^n-1 - 2·a(n-1), n>0, with a(1) = 1. A238315

Triangle read by rows: T(n,k) (0 <= k <= ceiling(n/2)-2) is the number of (1,1) steps starting at level k in all peakless Motzkin paths of length n (can be easily translated into RNA secondary structure terminology). A110238

The bisection of A238315 that remains constant with changes in the offset of the exponent of the second term. A239367

Lengths of largest face diagonal in primitive Euler bricks or Pythagorean cuboids: possible values of max(d, e, f) for solutions to a² + b² = d², a² + c² = e², b² + c² = f² in coprime positive integers a, b, c, d, e, f. A306120

a(0)=1, a(n)=2ⁿ+n²-2·a(n-1). A82384

Primes p such that 79 is a square mod p. A38965
