OEIS Sequences

Triangle of coefficients of Chebyshev's T(n,x) polynomials (powers of·in increasing order). A53120

a(0) = 0; thereafter a(n) is the least integer (in absolute value) not yet in the sequence such that the absolute difference between a(n-1) and a(n) is a square; in case of a tie, preference is given to the positive value. A377091

Generalized sum of divisors function: excess of sum of odd divisors of n over sum of even divisors of n. A2129

a(n) = 2 - n. A22958

Powers of -2: a(n) = (-2)ⁿ. A122803

Expansion of (1-x)/(1 - 2·x + 2·x²). A146559
