Information Given:

Series: TKF 4, SJE 8, RID 12, QHC 16, ?

Logic:

Letters decrease by 1 each term (all three positions); numbers increase by 4.

Explanation:

Logic: Each letter shifts −1; number shifts +4.

First letters: T → S → R → Q → P

Second letters: K → J → I → H → G

Third letters: F → E → D → C → B

Numbers: 4 → 8 → 12 → 16 → 20

Next term = P G B 20

Final Answer: PGB 20

Final Correct Option: D

Logic: ​Letters follow (−2, +3, −4) pattern; numbers increase by +2 difference pattern.

Check letter pattern instead:

KFU → IIQ

K→I (−2)

F→I (+3)

U→Q (−4)

IIQ → ?

Apply same (−2, +3, −4):

I→G

I→L

Q→M

So missing term = GLM

​Given pattern numbers:

15 → 22 (+7)

22 → 31 (+9)

31 → 42 (+11)

42 → 55 (+13)

Increasing by +2 each time.

So missing number = 31

So, the missing term is: ​GLM-31

Thus, the correct option is: (d)

Information Given:

Series: BD 99, GI 97, LN 93, QS 87, ?

Logic: Letters +5 each time; numbers decrease by consecutive even numbers.

Explanation:

Letters (First letter pattern):

B → G (+5)

G → L (+5)

L → Q (+5)

Q → V (+5)

So first letter = V

Second letters:

D → I (+5)

I → N (+5)

N → S (+5)

S → X (+5)

So second letter = X

Now numbers:

99 → 97 (−2)

97 → 93 (−4)

93 → 87 (−6)

87 − 8 = 79

Required term = VX 79

Final Answer: VX 79

Final Correct Option: A

Information Given:

Series:

LOH 1, JMG 4, HKF 9, FIE 16, ?

Logic:

• Each letter in the cluster moves −2 from the previous term (position-wise).

• Numbers follow 1², 2², 3², 4² → next = 5².

Step-by-step:

Letters:

LOH → JMG → HKF → FIE → DGD

(L→J→H→F→D ;

O→M→K→I→G ;

H→G→F→E→D)

Numbers:

1, 4, 9, 16 → 25

So, missing term = DGD 25

Final Answer: DGD 25

Final Correct Option: (D)

Information Given:

Series: PK23, OJ34, NI45, MH56, ?

Logic:

Letters decrease by 1 each step; numbers increase by 11.

Explanation:

Logic: Apply same pattern to letters and numbers.

Step-by-step:

Letters:

P → O → N → M → L

K → J → I → H → G

Numbers:

23 → 34 → 45 → 56 → 67 (+11 each time)

So the missing term = LG67

Final Answer: LG67

Final Correct Option: (C)

Information Given:

Series (Left → Right):

@ 2 % * 4 2 & £ % 1 £ & 9 7 & 9 7 $ 9 1 $ 2

Condition: N–S–S pattern; ignore others.

Logic:

Look for Number – Symbol – Symbol pattern.

Explanation:

Logic: Check each symbol one by one.

@ 2 % * 4 2 & £ % 1 £ & 9 7 & 9 7 $ 9 1 $ 2

Final Answer: 3

Final Correct Option: (C)

Information Given:

Series:

KDG 19, LEH 30, MFI 41, NGJ 52, ?

Logic:

Letters shift position-wise with alternating patterns; numbers increase by +11.

Explanation:

Logic: Analyze letters column-wise and numbers separately.

Step-by-step (Letters):

First letters: K → L → M → N → O (+1 each)

Second letters: D → E → F → G → H (+1 each)

Third letters: G → H → I → J → K (+1 each)

So next letter-cluster = OHK

Step-by-step (Numbers):

19 → 30 → 41 → 52 → ?

Each step = +11

52 + 11 = 63

Final Answer: OHK 63

Final Correct Option: C

Information Given:

Series:

BIP 104, ELS 97, HOV 90, KRY 83, NUB 76, ?

Logic:

Letters move forward by +3 each step; numbers decrease by 7.

Explanation:

Logic: Apply +3 alphabetical shift to each letter and −7 to numbers.

Step-by-step:

B→E→H→K→N→Q

I→L→O→R→U→X

P→S→V→Y→B→E

Numbers:

104 −7 = 97
97 −7 = 90
90 −7 = 83
83 −7 = 76
76 −7 = 69

So next term = QXE 69.

Final Answer: QXE 69
​
Final Correct Option: (D)

Information Given IVP 16 → HQM 5 → GLJ −6 → ? → EBD −28

Logic:

Letters move −1, −2, −3 respectively at each step; numbers decrease by −11.

Explanation:

IVP → HQM (I→H −1, V→Q −5? actually stepwise pattern per position)

Track per position across terms:

1st letters: I → H → G → F → E (−1 each step)

2nd letters: V → Q → L → G → B (−5 each step)

3rd letters: P → M → J → G → D (−3 each step)

So missing cluster = FGG.

Numbers:

16 → 5 → −6 → ? → −28

Pattern: −11 each time

So ? = −17.

Final Answer: FGG −17

Final Correct Option: (A)

Logic: Number is increasing + 20 and letter is increasing + 3 place

For, number

22 + 20 = 42, 42 + 20 = 62, 62 + 20 = 82

For, letter

C + 3 = F, F + 3 = I, I + 3 = L

So, the missing term is 82L.

Thus, correct option is (a).
