Question

Which letter cluster can replace the question mark (?) to complete the given series:   
AZFX, EWHW, ?, MQLU, QNNT?

Accepted Answer

Let's analyze the given series: AZFX, EWHW, ?, MQLU, QNNT.

Step 1: Break each cluster into four letters and analyze each position separately.

Positions:
1st letters: A, E, ?, M, Q
2nd letters: Z, W, ?, Q, N
3rd letters: F, H, ?, L, N
4th letters: X, W, ?, U, T

Step 2: Find the pattern in each position.

1st letters: A(1), E(5), ?, M(13), Q(17)
Differences: 5-1=4, ?-5=?, 13-?=?, 17-13=4
Check if difference is consistent:
From A to E: +4
From M to Q: +4
So likely, the difference between E and ? and ? and M is also +4.
From E(5) +4 = 9 (I)
From I(9) +4 = 13 (M)
So the 1st letter of ? is I.

2nd letters: Z(26), W(23), ?, Q(17), N(14)
Differences: 23-26 = -3, ?-23=?, 17-?=?, 14-17 = -3
Check if difference is consistent:
From Z to W: -3
From Q to N: -3
So likely, the difference between W and ? and ? and Q is also -3.
From W(23) -3 = 20 (T)
From T(20) -3 = 17 (Q)
So the 2nd letter of ? is T.

3rd letters: F(6), H(8), ?, L(12), N(14)
Differences: 8-6=2, ?-8=?, 12-?=?, 14-12=2
Check if difference is consistent:
From F to H: +2
From L to N: +2
So likely, the difference between H and ? and ? and L is also +2.
From H(8) +2 = 10 (J)
From J(10) +2 = 12 (L)
So the 3rd letter of ? is J.

4th letters: X(24), W(23), ?, U(21), T(20)
Differences: 23-24 = -1, ?-23=?, 21-?=?, 20-21 = -1
Check if difference is consistent:
From X to W: -1
From U to T: -1
So likely, the difference between W and ? and ? and U is also -1.
From W(23) -1 = 22 (V)
From V(22) -1 = 21 (U)
So the 4th letter of ? is V.

Step 3: Combine the letters:
1st: I
2nd: T
3rd: J
4th: V

Step 4: Check options:
Option 1: IJTV
Option 2: JITV
Option 3: ITJV
Option 4: JTIV

Our derived cluster is ITJV, which matches Option 3.

Step 5: Re-check the order of letters in the options:
Our derived cluster is I (1st), T (2nd), J (3rd), V (4th) = ITJV
Option 3 is ITJV, which matches exactly.

Therefore, the correct answer is Option 3: ITJV.
