22,99,34,21,10,31,18,104,28,13,

• There should be 101 in place of 10 in the given series.
  Hence the series is like 22, 99, 34, 21, 101, 31, 18, 104, 28, 13, ?
  On dividing into three sub series: we will get three types of series which are described below,
  (22, 21, 18, 13), (99, 101, 104), (34, 31, 28)
  22 - 1 = 21, 99 + 2 = 101, 34 - 3 = 34
  21 - 3 = 18, 101 + 3 = 104, 31 - 3 = 28
  18 - 5 = 13, 104 + 4 = 108(Ans)

• The series are like this
  (22,21,18,13)(99,101,104)(3,31,28)
  The next term will be 99+2=101+ 3=104+4=108
  So the answer will be 108

• instead of 10 there should be 101 in series. and ans would be 108 as 99,101,104,108

• ans:(22,99,34),(21,101,31),(18,104,15)(?. .)
  22-1=1;21-3=18;18-5=13
  ans 13
