it have two sequence.
1st sequence is 14,20,32,
2nd sequence is 28,40,64,
in this, 1st sequence increase like +6,+12,+24,+48....
2nd sequence increase like +12,+24,+48........ - 13 years agoHelpfull: Yes(12) No(0)
- 14*2=28
28-8=20
20*2=40
40-8=32
32*2=64
64-8=56 - 9 years agoHelpfull: Yes(2) No(0)
- 14+6=20
20+12=32
