Nov 26, 2009 · O ( (1/2 (1+sqrt (5)))^n) The reason is simple: the function Fibonacci (1) will execute as many times as is the size of the Fibonacci number. Now, the n-th Fibonacci number is asymptotically. (1/2 (1+sqrt (5)))^n = approx 1.6^n. Last edited on Nov 26, 2009 at 12:12pm. Solution: The formula to calculate Fibonacci number using Golden ratio is X n = [φ n – (1-φ) n]/√5. We know that φ is approximately equal to 1.618. n= 6. Now, substitute the values in the formula, we get. X n = [φ n – (1-φ) n]/√5. X 6 = [1.618 6 – (1-1.618) 6]/√5. X 6 = [17.942 – (0.618) 6]/2.236. X 6 = [17.942 – 0.056]/2.236. X 6 = 17.886/2.236. X 6 = 7.999. X 6 = 8 (Rounded value) The Fibonacci number in the sequence is 8 when n=6.
