• 1,1,3,9,11,121,124,....
  look out the series square the no and add 1,2,3, increasingly...
  1 first no
  1^2=1second no
  2nd no+2=3
  3^2=9
  9+2=11
  11^2=121
  121+3=124

• 1 , 1^2 , 1^2+2=3 , 3 ,3^2 ,3^2+2=11
  11 ,11^2, 11^2+2=123

• 1^2=1
  3^2=9
  11^2=121
  
  and Difference between series is 3-1=2^1=2
  11-3=2^3=8
  power are 1,3,5 so ans is 32^2=1024

• here the combination goes like this n3+n2
  
  1*1 =1
  1+2=3
  3*3=9
  9+2=11
  11*11=121
  121+2=123
