COMMENT
|
The first term is always odd and may be prime.
|
|
FORMULA
|
Let f(n) = prime(n) + prime(n+1) f1(n) = f(n)+f(n+1) : SS of order 1 Then f2(n) = f1(n)+f1(n) : SS of order 2 is the general term of this sequence.
|
|
EXAMPLE
|
The first two terms of SS order 1 is 13 and 20. 13+20 = 33 the first term of the sequence.
|
|
PROGRAM
|
(PARI) g(n) = for(x=1, n, print1(f2(x)", ")) f(n) = return(prime(n)+prime(n+1)) f1(n) = return(f(n)+f(n+1)) f2(n) = return(f1(n)+f1(n+1))
