a).3,6,13,26,33,66,_ b).0, 1,2,13 ,6,33 ,12, 63,20, 103,_

• puzzle (A) soln is
  break the terms in two parts 3,13,33,63 has increasing diff of 10,20,30..n so on
  second part 6,26,66 has increasing diff of 20,40,60...so the series ls 3,6,13,26,33,66,63.
  solution of puzzle(B)..proceed in same way as puzzle (A)..
  0 2 6 12 20 incresing diff of addative 2 ie 2,4,6,8,10
  1 13 33 63 103 incresing diff of 10,20,30,40,50
  so series is 0,1,2,13,6,33,12,63,20,103,30,153...

• ans for puzzle a will be 73
  becoz we can get a series like this
  3*2=6
  13*2=26
  33*2=66
  so on
  in that way cannot find the next term..
  now 13-6=7
  and 33-26=7
  in the same way x-66=7
  so x=73
  and the next number of 73 will be 73*2=146
  so the series will be
  3,6,13,26,33,66,73,146 so on

• b) 28,153
  0,1,2,13,6,33,12,63,20,103,_
  0,2,6,12,20..difference is increasing by 2,4,6,8..so next number is 28.
  1,13,33,63,103,..difference is increasing by 10,20,30,40,50..so next number is 153.
