1, 1×1=1, 1×2=2, 2×3=6, 6×4=24, 24×5=120
1, 1, 2, 6, 24, 120

0+5=5, 5-1=4, 4+5=9, 9-1=8, 8+5=13, 13-1=12, 12+5=17, 17-1=16
0,5,4,9,8 (aici trebuie sa fie 8, nu 18), 13, 12,17, 16

2×3=6, 6-2=4, 4×3=12, 12-2=10, 10×3=30, 30-2=28, 28×3=84
2, 6, 4, 12, 10, 30, 28, 84

2×2=4, 4-1=3, 3×2=6, 6-1=5, 5×2=10, 10-1=9, 9×2=18, 18-1=17
4, 3, 6, 5, 10, 9, 18, 17
