f(2)=3
f(3)=8
f(4)=17
f(n+3) = 2*f(n+2) + 2*f(n+1) – 4*f(n)

Roots of polynomials of degree 5 and higher often can’t be expressed exactly using things like plus, minus, multiplication, and roots (this is the Abel-Ruffini theorem), so it would be quite a surprise if this root of a degree-71 polynomial could be.
