  Start with sequence:
   0,1,2,3,4,5,6,7,8,9,10,...
  Sum each term a(n) with a(n+2):
   2,4,6,8,10,12,14,16,18,...
  Repeat the procedure:
   8,12,16,20,24,28,32,...
  24,32,40,48,56,...
  64,80,96,...
 160,...

First terms in each line makes the SEQ
 0,2,8,24,64,160,
with a(n) = n*2^n ( = A036289)
