Question 30

English: BDFH, IKMO, PRTV, ?

(a) WYAC

(b) WXYA

(d) WYZA

Answer: (a) WYAC

Explanation: Each block consists of 4 alternate letters:

BDFH starts at $2$, jumps of $+2$.
IKMO starts at $9$, jumps of $+2$.
PRTV starts at $16$, jumps of $+2$.
The next block starts after $V (22)$, which is $W (23)$, and jumps of $+2$: $W (23) \xrightarrow{+2} Y (25) \xrightarrow{+2} A (1) \xrightarrow{+2} C (3)$. The next term is WYAC (Option a).

Question 31

English: WVTSQPNMKJ??

(a) HG

(b) IL

(d) GF

Answer: (a) HG

Explanation: The sequence consists of alphabetical pairs in reverse order, skipping every third letter: W, V (U skipped), T, S (R skipped), Q, P (O skipped), N, M (L skipped), K, J (I skipped), H, G. Thus, the next two letters are HG (Option a).

Question 32

English: bcde, ebcd, debc, cdeb, ??

(a) dcbe

(b) bcde

(d) dbce

Answer: (b) bcde

Explanation: This is a shifting cyclic string pattern:

bcde
ebcd (last letter shifted to front)
debc (last letter shifted to front)
cdeb (last letter shifted to front)
Next shift moves b back to the front, producing bcde (Option b).

3rd letter: $A (1) \xrightarrow{+2} C (3) \xrightarrow{+2} E (5) \xrightarrow{+2} G (7)$ The next term is SHG (Option a).

Question 37

English: D, F, I, , ?

(a) P

(b) Q

(d) T

Answer: (c) R

Explanation: The sequence consists of single letters with increasing gaps:

$D (4) \xrightarrow{+2} F (6)$ (gap of 1: E)
$F (6) \xrightarrow{+3} I (9)$ (gap of 2: G, H)
$I (9) \xrightarrow{+4} M (13)$ (gap of 3: J, K, L)
$M (13) \xrightarrow{+5} R (18)$ (gap of 4: N, O, P, Q) Thus, the next missing letter represented by the question mark is R (Option c).
