Directions: In the following question, an alphanumeric series is give...
In each term, the first element is a letter. The letters are moved two steps backwards to get the letter in the next term. The second element is a number, and these numbers follow the reverse sequence of perfect squares, starting from 12.
W - 2 = U
U - 2 = S
S - 2 = Q
Q - 2 = O
122 = 144
112 = 121
102 = 100
92 = 81
82 = 64
Therefore, the required combination is 'U121'.

Directions: In the following question, an alphanumeric series is give...
Alphanumeric Series:
The given series is an alphanumeric series consisting of numbers and alphabets. The missing term needs to be identified based on the pattern followed in the series.

Pattern Analysis:
Let's analyze the given series to identify the pattern followed:

W144, ?, S100, Q81, O64

1. The first letter of each term is in alphabetical order: W, S, Q, O.
2. The second letter of each term is a number: 144, ?, 100, 81, 64.

Pattern in the Numbers:
Let's focus on the pattern in the numbers:

1. The numbers are decreasing from left to right: 144, ?, 100, 81, 64.
2. The numbers are perfect squares.

Pattern in the Alphabets:
Now, let's analyze the pattern in the alphabets:

1. The first letter of each term is moving one step backward in the alphabetical order: W, S, Q, O.
2. The second letter of each term is moving one step forward in the alphabetical order: 144, ?, 100, 81, 64.

Identifying the Missing Term:
Based on the observed patterns, we can determine the missing term:

1. The first letter of the missing term should be one step backward from "S," which is "R."
2. The second letter of the missing term should be one step forward from the number 100, which is "U."
3. The missing term should be a perfect square.
4. Therefore, the missing term is "U121."

Conclusion:
Based on the pattern analysis, the missing term in the given series is "U121."
