Step 1: Look at each position separately

Write letters vertically:

1st letters:
D, Z, ?, R, N

2nd letters:
K, G, ?, Y, U

3rd letters:
C, Y, ?, Q, M

Step 2: Analyse 1st letters

D (4)
Z (26)
?
R (18)
N (14)

Pattern:

4 → 26 = −4 (cyclic back)
26 → 22 = −4
22 → 18 = −4
18 → 14 = −4

So the missing letter is:

Z − 4 = V (22)

First letter = V

Step 3: Analyse 2nd letters

K (11)
G (7)
?
Y (25)
U (21)

Pattern:

11 → 7 = −4
7 → 3 = −4
3 → 25 = −4 (cyclic)
25 → 21 = −4

So missing letter:

G − 4 = C (3)

Second letter = C

Step 4: Analyse 3rd letters

C (3)
Y (25)
?
Q (17)
M (13)

Pattern:

3 → 25 = −4 (cyclic)
25 → 21 = −4
21 → 17 = −4
17 → 13 = −4

So missing letter:

Y − 4 = U (21)

Third letter = U

Final Answer:
