%N Sum_{i=1,...,n} LookAndSay(i).

%C A question related to this sequence: prove the convergence or divergence of the infinite series Sum_{i=1,2,3,....} 1/LookAndSay[i]. (Numerical experiments suggest that this diverges slowly.)

%e a(2) = LookAndSay(1) + LookAndSay(2) = 11 (one "1") + 12 (one "2") = 23.
