FORMULA

First differences of A005370 = F(F(n+1)+1). - Antonio G. Astudillo (afg_astudillo(AT)hotmail.com), Nov 17 2002

EXAMPLE

a(0) =0, a(1) = 1, a(2) = 1, a(3) = 2+3 = 5, a(4) = 5+8+13=26, etc.

MAPLE

with(combinat, fibonacci): A077537 := n -> fibonacci(fibonacci(n+2)+1)-fibonacci(fibonacci(n+1)+1);

# second Maple program:

F:= n-> (<<0|1>, <1|1>>^n)[1, 2]:

a:= n-> F(F(n+2)+1)-F(F(n+1)+1):

seq(a(n), n=0..14);  # Alois P. Heinz, Nov 05 2015
