(1) In the series A2Z, C4X, E8V, ____, I32R, what comes next?

(a) G16T
(b) H16T
(c) G16T
(d) G16U

Correct Answer: (c) G16T
The pattern in the series involves increasing the first letter by two steps in the alphabet (A to C to E, etc.), doubling the number each time (2 to 4 to 8, etc.), and decreasing the last letter by two steps (Z to X to V, etc.). So the next sequence should be G16T.
\[ \text{If } L_1, L_2, L_3 \text{ are the first, second, and third letters respectively, then the pattern follows: } L_1 = L_1 + 2, N = N \times 2, L_3 = L_3 – 2 \]

(2) If the series is Z1A, X2C, V6E, ____, R24G, what should fill the blank?

(a) T12E
(b) T12F
(c) U12F
(d) T10F

Correct Answer: (b) T12F
This series follows a pattern where the first letter decreases by two positions in the alphabet, the number is multiplied by 2, and the last letter increases by one position. Therefore, the missing sequence is T12F.
\[ \text{With } L_1, N, L_2 \text{ as the first letter, number, and second letter respectively, the rule is: } L_1 = L_1 – 2, N = N \times 2, L_2 = L_2 + 1 \]

(3) In the series B3D, F7H, J11L, ____, P19R, what comes next?

(a) N15P
(b) N15M
(c) O16N
(d) O15N

Correct Answer: (b) N15M
The pattern in the series involves increasing the first letter by four steps in the alphabet (B to F to J, etc.), adding 4 to the number each time (3 to 7 to 11, etc.), and increasing the last letter by two steps (D to H to L, etc.). So the next sequence should be N15M.
\[ \text{If } L_1, N, L_2 \text{ are the first letter, number, and second letter respectively, then the pattern follows: } L_1 = L_1 + 4, N = N + 4, L_2 = L_2 + 2 \]

(4) If the series is A3C, E6E, I9G, ____, M15I, what should fill the blank?

(a) Q12K
(b) Q14K
(c) R12K
(d) R14K

Correct Answer: (a) Q12K
This series follows a pattern where the first letter increases by four positions in the alphabet (A to E to I, etc.), the number increases by 3 each time (3 to 6 to 9, etc.), and the last letter increases by two positions. Therefore, the missing sequence is Q12K.
\[ \text{With } L_1, N, L_2 \text{ as the first letter, number, and second letter respectively, the rule is: } L_1 = L_1 + 4, N = N + 3, L_2 = L_2 + 2 \]

(5) In the series X2W, T6U, P12V, ____, J30W, what comes next?

(a) E30X
(b) G24X
(c) H30X
(d) F24X

Correct Answer: (b) G24X
The pattern in the series involves decreasing the first letter by four steps in the alphabet (X to T to P, etc.), doubling the number each time (2 to 6 to 12, etc.), and increasing the last letter by one step (W to U to V, etc.). So the next sequence should be G24X.
\[ \text{If } L_1, N, L_2 \text{ are the first letter, number, and second letter respectively, then the pattern follows: } L_1 = L_1 – 4, N = N \times 2, L_2 = L_2 + 1 \]
