You are right. The given program for A050200 does not match the
definition, and it computes a value that is quite tedious to
express with language. The choice of 'x','x+1','x+3' makes the
sequence arbitrary, as well, so I second your demand.
If Neil wants to keep it he must live with a definition like
%N A050200 a(n) = p(n)+p(n+1)+p(n+2) if p(n) is the smaller of a
twin prime, otherwise p(n)+2*p(n+1), with p(n) the n-th prime.
