in this series which one is wrong
828, 424, 220, 116, 64, 33
(a) 220 (b) 64
(c) 33 (d) 116

• ans=(b) 64
  828,424,220,116,64,33
  its difference,
  404,204,114,52,31 (here we can see similarity among 404,204,114
  =25*16+4,25*8+4,25*4+4)
  (it seems like here multiplication term is taken as 2^4,2^3,2^2,2^1,2^0)
  so term 64 can be wrong. now,
  116-(25*2+4)= 62, let's check it => 62-(25*1+4)=33(which is given as last term)
  => 828,424,220,116,62,33 is correct series
