How to Solve Wrong Number Series | Reasoning Short Tricks in hindi | Reasoning for CLAT/SSC/SBI/IBPS/RRB/BBA/BCA 2020 | Short Tricks by Rajesh Choudhary Sir
The chapter consists of questions in which series of numbers or alphabetical letters or combinations of both are given, which are generally called the terms of the series. These terms follow a certain pattern throughout the series. The candidate is required to study the given series, identify the pattern followed in the series and either complete the given series with the most suitable alternative or find the wrong term in the series.

Type - I Number series

Example: 1. 4, 8, 28, 80, 244, ?
a. 278 b. 428 c. 628 d. 728
Solution:

Example: 2. 0, 6, 24, 60, 120, 210, ?
a. 240 b. 290 c. 336 d. 504
Solution:
Example: 3. 1, 4, 27, 16, ?, 36, 343
a. 25 b. 87 c. 120 d. 125
Solution:

Type - II Alphabet series
Example: 4. Which tern comes next in the sequence : AC, FH, KM, PR, ?
a. UW b. VW c. UX d. TV
Example: 5. Which tern comes next in the series: YEB, WFD, UHG, SKI, ?
a. QOL b. QGL c. TOL d. QNL
Type - III Alphabet Numeric Series
Example: 6. Find the term which does not fit into the series given below:
G4T, J10R, M20P, P43N, S90L
a. G4T b. J10R c. M20P
d. P43N e. S90L
Type - IV Continuous pattern Series
Example: 7. aab —aaa—bba—
a. baa b. abb c. bab
d. aab e. bbb
Solution: We proceed step by step as shown below:
1. The first blank space should be filled in by ‘b’ so that we have two a’s followed by two b’s .
2. The second blank space should be filled in either by ‘a’ so that we have four a’s followed by two b’s, or ‘b’ so that we have three a’s followed by three b’s.
3. The last space must be filled in by ‘a’.
4. Thus, we have two possible answers: ‘baa’ and bba’. But, only ‘baa’ appears in the alternatives. So, the answer is (a).
5. In case, we had both the possible answers in the alternatives, we would have chosen the one that forms a more prominent pattern, which is aabb/aaabbb/aa. Thus, our answer would have been ‘bba’.
