2)At a certain given relative position in the sequence, it is need to determine the element.

3)By converting the hidden part in relation to the position of the elements in the sequence, it is required to complete a series consisting of terms formed by a combination of the elements of the sequence.

4)By finding the common property which other combinations share as per their positions in the given sequence, It is required to find the odd combination from among a given set of combinations of elements.

5)To determine the analogical relationship between a given pair of combination of elements, later find a combination which carry same relationship with another given combination.


Example :-

Study the following arrangement of symbols, letters and numbers. Answer the following questions?

2 P J @ 8 $ L B 1 V # U 6 δ G W 9 K C D 3 © . € 5 F R 7 A Y 4

1. Which one among QK5, L6D, PLδ, 1G©, K€4 doesn’t belong to the group?

Solution :-

Given series is

2 P J @ 8 $ L B 1 V # U 6 δ G W 9 K C D 3 © . € 5 F R 7 A Y 4

QK5: Gap between Q & K is 6, K & 5 is 7

L6D: Gap between L & 6 is 6, 6 & D is 7

PLδ: Gap between P & L is 5, L & δ is 7

1G©: Gap between 1 & G is 6, G & © is 7

K€4: Gap between K & € is 6, € & 4 is 7

Therefore, PLδ doen’t belong to the same group.


2. P@L is to Y75 in the same way what is $1# ?

Solution :-

Given series is

2 P J @ 8 $ L B 1 V # U 6 δ G W 9 K C D 3 © . € 5 F R 7 A Y 4

P@L is to Y75

Here, P is second from left whereas Y is second from right.

@ is fourth from the left whereas 7 is fourth from right.

L is seventh from the left whereas 5 is seventh from right.

Similarly consider $1#

If $ is sixth from left, then sixth letter from right is F.

If 1 is ninth from left, then letter from right is dot.

If # is eleventh from left, then eleventh letter from right is 3.

Therefore, F.3 is the same as $1#.
