OEIS Sequences

Partial sums of A027035. A27036

Let sequence B_n={b_m} be defined by: b₁=prime(n), b₂=prime(n+1); for m>=3, b_m=b_m-2+b_m-1 if b_m-2+b_m-1 is not semiprime, otherwise b_m is the least prime divisor of b_m-2+b_m-1. Then a(n) is the maximal term of sequence B_n, or a(n)=0 if B_n is unbounded. A221218

Start with 1, then alternately double or add 2. A99942
