For a 6 number sequence, supplying the first 3 numbers as an initial condition
might be an unfair advantage. Besires, the true
answer is obvious:
4 _11.15 26.875 _14.625 3.125 _0.225 p. i. 6
4 8 15 16 23 42
Which is only comprised of 7 numbers and two functions: a mere 50% worse than
the original series :)
