Operasi Dasar Utama : Penjumlahan
T(n) = T(n-1) + T(n-2) dimana
n > 2
T(n) = 1 + 1 (1 + T(n-2) + T(n-3))
T(n) = 1 + 2(1 + T(n-3) + T(n-4))
T(n) = 1 + 3(1 + T(n-4) + T(n-5))
T(n) = ...
T(n) = n + (1 + T(n-n) + T(n – (n-2))
T(n) = n + 1 + T(0) +
T(n – (n-2))
T(n) = n + T(n – (n-2))
T(n) = n + (n-(n-2))
Jadi, T(n) = n +
(n-(n-2))
