Answer 2

Answer:

9, 18, 55, 216, 1080, 6480

wrong number = 55

Step-by-step explanation:

55 is the wrong number  

According to me  

This series is multiple of 9, 18, 55, 216, 1080, 6480

55 is replace by 54

9*2=18

18*3=54

54*4=216

216*5=1080

1080*6=6480

The accurate series become  

9    18    54    216    1080   6480  this is right series.
