      Answer : 2) Y88B
      Solution : The first letter moves two steps forward. The last letter moves one steps backward. The number series runs as follows :
      1 x 1 + 1 = 2
      2 x 2 + 2 = 6
      6 x 3 + 3 = 21
      21 x 4 + 4 = 88.

    • Discussion in forum
      Answer : 4) 4374
      Solution : We can see the given series is in G.P.
      as 2*3 = 6, 6*3 = 18, 18*3 = 54
      So a = 2 , r = 3
      nth term in G.P. is ar(n - 1)
      = 2*3(8 - 1)
      = 2*37
      = 2*2187 = 4374
