A084962 Iterations of the Fibonacci sequence starting at 6. 1
6, 8, 21, 10946 (list; graph; refs; listen; history; internal format)
OFFSET

0,1

COMMENTS

a(4)=1.695... * 10^2287. This sequence is of interest because the sequences with this recurrence and a(0) in {0,1,2,3,4} all converge to 1 and the sequence with a(0)=5 is constant.

FORMULA

a(0)=6, a(n+1)=Fibonacci(a(n))

EXAMPLE

a(3)=Fibonacci(a(2))=Fibonacci(21)=10946.

MATHEMATICA

a[m_] := Module[{ex = 6}, Do[ex = Fibonacci[ex], {m}]; ex] Table[a[m], {m, 0, 4}]

CROSSREFS
