  without options we are imagining our own solutions don't know whether we got correct answer or not

• series followed as 3^2,3,2^2,2
  the diff,between 9 and 18 is 9 so it is 3^2
  the diff,between 18 and 21 ia 3
  same as like the difference b/w 21 and 25 is 4=2^2
  so the difference should be 2,so the answer is 22
