Reversion of g.f. for Fibonacci numbers 1, 1, 2, 3, 5, .... A7440

Excess of the number of even Motzkin n-paths (A107587) over the odd ones (A343386). A343773

G.f. A(x) satisfies: 2ⁿ - 1 = ∑_k=0..n [x^k]A(x)ⁿ and also satisfies: (2+z)ⁿ - (1+z)ⁿ + zⁿ = ∑_k=0..n [x^k](A(x)+z·x)ⁿ for all z, where [x^k]A(x)ⁿ denotes the coefficient of x^k in A(x)ⁿ. A100223

a(-1) = 1 and g.f. A(x) satisfies A(x) - 1/A(x) = 1/x - 1. A214649
