• Reverse the number and divide by next number.
  54 ==> 45/15 == 3
  78 ==> 87/29 == 3
  900 ==> 9/(A) == 3
  A = 3
  So the series is 54,15,78,29,900,3

• First number is the reverse of 3 times the second number(15*3=45 so reverse is 54)
  similarly,
  Third number is the reverse of 3 times the fourth number(29*3=87 so reverse is 78)
  Fifth number will be the reverse of 3 times the sixth number(3*3=009 so reverse is 900)
  so,
  answer is '3' in the next term
