200, 400, 8000, 16000, 320000.

Regula :

8000 : 400 = 20

16000: 8000 = 2

(observam ca ratia e 2 si 20)

200 x 2 = 400

400 x 20 = 8000

8000 x 2 = 16000

16000 x 20 = 320000

960000, 48000, 2400, 120, 6.

Regula :  

48000 : 2400 = 20

2400 : 120 = 20

(observam ca ratia e 20 )

48000 x 20  = 960000

48000: 20 = 2400

2400 : 20 = 120

120 : 20 = 6
