ALPHA NUMERIC SEQUENCE PUZZLE


## In this type of questions, a jumbled sequence of some letters, numbers and symbols is given, followed by questions based on it.
 The questions asked may be any of the following types:
1) To find elements (letters, numbers of symbols) satisfying certain conditions in the given sequence.
2) to determine the element at a certain given relative position in the sequence.
3) to complete the series consisting of terms formed by a combination of the elements of the sequence, by deciphering the hidden pattern in relation to the position of the elements in the sequence.
4) to find the odd combination from among a given set of combinations of elements, by finding the common property which other combinations as share as per their positions in the given sequence.
5) to find the analogical relationship between a given pair of combinations of elements, and then find a combination which holds same relationship with another given combination.
     REMEMBER:
 you have to study the given terms be letters, numbers or symbols in relation to their location in the given sequence, and not as per their status in English alphabet or Indian number system.
