RE: Hi friendz, This sequence is from ibm pape...
 
the digit count of the sequence isof the form.....  (ie)1+5=6    3+0=3     2+8=1 etc.
    6    3    1    7    2    7    1           .....so the remaining two nos. should have the count 3 and 6 respectively.....
 moreover the flow of the sequence is "the second no. is greater than first and all other are less upto the no. with count 2(i.e) middle no.

and the no. next to middle no. (i.e)34 is greater than 20...
so all others should be less than 34....

on keeping all these in mind... v ll have  21          :    2+1=3
                                                               15         :     1+5=6

so the sequence is   15  30  28  25  20  34  28  21  15
