find the next number in the series 92,\ 93,\ 97,\ 106, ?

Explanation:

  1. let the given numbers belong to a series 'A' then we have,                                       a_1=92,\ a_2=93,\ a_3=97,\ a_4=106,\ a_5=?                                                                                d_1=93-92=1\\d_2=97-93=4\\d_3=97-106=9                    
  2. now we have a second series let it be denoted by 'B'  (1,4,9,....) then we have,     d_1'=4-1=3, \ \ \ \ \ \ d_2'=9-4=5  
  3. hence, we have a third series let it be 'C' (3,5,....). hence, C is series of odd numbers starting from 3. therefore we get, d_3'=7    
  4. now from series B we have, d_3'=d_4-d_3\ \ \ \ \ \ \ ->d_4=d_3+d_3'                                         hence, d_4= 9+7=16    
  5. now from series A we have, d_4=a_5-a_4\ \ \ \ \ \ \ ->a_5=a_4+d_4                                 hence, a_5=106+16=122      
  6. next number is  122
