%F a(n) is asymptotic to tau^(2tau)*(2n)^(tau1) and more precisely it seems that a(n) = round(tau^(2tau)*(2n)^(tau1)) +(1, +0 or +1) where tau is the golden ratio.
%e Read 2,2,4,4,6,6,6,6,8,8,8,8,10,10,10,10,10,10 as (2,2),(4,4),(6,6,6,6),(8,8,8,8),(10,10,10,10,10,10) count occurrences between 2 parentheses, gives 2,2,4,4,6,... which is the sequence itself.
