Remark 1.1 (a) It is to be born in mind that a sequence (a 1;a However, because of this, at each time-step, a multidimensional nonlinear equation must be solved. Generating Functions Given a sequence (a0, a1, a2, a3,.) If square 3 is covered by 3-8, then the following dominoes are forced in turn: 4-9, 10-15, 19-20, 23-24, 17-22, and 13-18, and now no domino can cover square 14. Question 824142: The sequence (An) is defined by A0=1 and A (n+1)= 2An +2 for n=0,1,2.. What is the value of A3?
