COMMENTS

For sufficiently large terms of a random Fibonacci sequence, the powers of Viswanath's constant approximate the absolute value of the terms in such a sequence (with a few notable exceptions).

LINKS

Table of n, a(n) for n=0..49.

Eric Weisstein, Random Fibonacci sequence at MathWorld

FORMULA

a(n) = floor(v^n), where v = 1.1319882487943 as given by A078416.

EXAMPLE

a(7) = 2 because V^7 is approximately 2.381734947432 and floored that is 2.

MATHEMATICA

V = 1.1319882487943; Table[Floor[V^n], {n, 0, 49}]
