Hello! i'm from Italy, and i'm trying to solve this equation:



T(n) = T(n - 1) + T(n - 2) + n

my result is that the big theta notation of this equation is Θ(2^n) and the big O notation is O(2^n) * (n)

but i think that i made something wrong. Can someone explain me how to calculate the tree main landau symbols of this equation? (O, Ω and Θ)? i need some help because i have the test not too far away. Thank you!
