Hello MathFun & SeqFans,
Start S = 2, 9,...
Next term is (2*9)mod(2+9)
18 mod 11 = 7
S = 2, 9, 7,...
Next term is (9*7)mod(9+7)
63 mod 16 = 15
S = 2, 9, 7, 15,...
Next term is (7*15)mod(7+15)
105 mod 22 = 17
S = 2, 9, 7, 15, 17,...
Next term is (15*17)mod(15+17)
255 mod 32 = 31
S = 2, 9, 7, 15, 17, 31,...
Next term is (17*31)mod(17+31)
527 mod 48 = 47
S = 2, 9, 7, 15, 17, 31, 47,...
Does this end in a loop?
If yes, is there another start
which doesn't?
Best,
É.
