56,89,33,21,57,88,35,19,60,85,30,?

• sorry again
  
  divide the series like
  
  56, 89, 33, 21
  57, 88, 35, 19
  60, 85, 30, ?
  
  observe 1st column +1 and +3 to get next column value
  observe 2nd column -1 and -3 to get next column value
  
  observe 3rd column +2 and -5 to get next column value
  so we should do -2 and +5 in the last column
  
  so last column would be 21-2=19 and 19+5=24
  
  24 is the answer

• Answer is 39.
  56+1 = 57 [5th term]
  89-1 = 88 [6th term]
  33+2 = 35 [7th term]
  21-2 = 19 [8th term]
  57+3 = 60 [9]
  88-3 = 85 [10]
  35+4 =39(Ans)

• groups: (56,57,60),(89,88,85), (33,35,30), (21,19,?)
  56+1=57, 57+3=60
  89-1=88, 88-3=85
  then
  33+2=35, 35-5=30
  21-2=19 so 19+5=24 (ans.)

• answer is 14 ... Explanation :
  56,57,60 have +1, +3 difference
  89,88,85 have -1, -3 difference
  like
  33,35,30 have +2, +5 difference
  21,19,? must have -2, -5 difference
  so answer is 19 - 5 = 14.
