2 9 3 1 8 4 3 6 5 7 ?⁠⁠⁠⁠

• the first series is 2,3,4,5....
  the second series is 9*1=9,
  9*2=18,
  18*2=36,

• the answer is 2
  solution is:-
  2-9-3-1 8-4-3 6-5-7 2-6
  there is an alternating series of 2,3,4,5,6....and so on.
  then there is alternating series of twice of each number i.e.
  9,18,36,72,144.... and so on.
  so the next digit after 7 is 2.

• 2 9 3 1 8 4 3 6 5 7 ?
  second term is 9
  fourth term =9*2=1 8 as fourth and fifth term
  similarly, 18*2=3 6 as 7th and 8th term
  hence, 36*2 = 7 2 as 10th and 11th term so and so....
  another series increases by as 2 3 4 5 .....
