1. Series consisting of Perfect Squares:

A series based on Perfect squares is most of the times based on the perfect squares of the numbers in a specific order & generally one of the numbers is missing in this type of series.

Ex:  13    15    21    33    53    ?

Sol:
 Series Pattern Given Series 13 13 13 + 12 + 1 15 15 + 22 + 2 21 21 + 32 + 3 33 33 + 42 + 4 53 53 + 52 + 5 83 ?

In a two step Arithmetic series, the differences of consecutive numbers themselves form an arithmetic series.
Ex: 9     13     22     36     55    ?

Sol:
Series Pattern:

 Series I : 9 13 22 36 55 79 Series II : + 4 + 9 + 14 + 19 + 24 Series III : + 5 + 5 + 5 + 5
