%N Twice A113473.
%C Arises in a renewal problem. Suppose X(1), X(2), ... are independent and identically distributed random variables with P(X = 1) = P(X = 2) = 0.5, and let N(n) denote the first value of k such that X(1)*X(2)*...*X(k) > x. Then a(n) gives the expected value of N(n), n = 1, 2, 3, ...
%Y Cf. A113473.
