Guess pattern:
1
11
21
1211
111221
(first try to guess the next number!)

• ans-312211
  explanation-
  in the 1st column 1 is written and in next column 11 is written because in the previous column 1 is written 1 time.
  again,in next column 21 comes because 1 is written 2 times.
  so in last column 312211 will come because 1 is repeated 3 times,then 2 is repeated 2 times and then again 1 is repeated a single time
