(6)

Pattern:
G → 7, T → 20, I → 9, O → 15, ?
Answer: L → 12
Explanation: The pattern is not a simple sequence but the letters are placed in a random order where the number correlates to the letter’s position.

(7)

Pattern:
A → 1, B → 2, C → 4, D → 8, E → 16, ?
Answer: 32
Explanation: The numbers follow a doubling pattern. After E → 16, the next number is 32.

(8)

Pattern:
F → 6, I → 9, M → 13, O → 15, ?
Answer: S → 19
Explanation: The numbers follow an increasing order, but some letters are skipped in the alphabet. After O → 15, S → 19.

(9)

Pattern:
A → 1, E → 5, I → 9, O → 15, U → ?
Answer: 21
Explanation: The letters are vowels, and the numbers correspond to their positions in the alphabet (A = 1, E = 5, I = 9, O = 15, U = 21).

(10)

Pattern:
1 → A, 2 → C, 3 → E, 4 → G, 5 → ?
Answer: I
Explanation: The letters follow an increasing sequence where each letter skips one letter after the previous. After G → I.

(11)

Pattern:
S → 19, T → 20, U → 21, V → 22, W → ?
Answer: 23
Explanation: The letters correspond to their position in the alphabet, and the numbers follow the sequence. After V → 22, W → 23.

(12)

Pattern:
A → 1, B → 4, C → 9, D → 16, E → 25, ?
Answer: 36
Explanation: The numbers correspond to the squares of the positions in the alphabet. After E → 25, the next number is 36.

(13)

Pattern:
K → 11, L → 12, M → 13, N → 14, O → ?
Answer: 15
Explanation: The letters are in sequential order, so after N → 14, O → 15.

(14)

Pattern:
A → 1, B → 2, C → 4, D → 8, E → 16, F → 32, ?
Answer: 64

(15)

Pattern:
4 → 16, 5 → 25, 6 → 36, 7 → 49, 8 → ?
Answer: 64
Explanation: The numbers are squares of the corresponding numbers: 4^2 = 16, 5^2 = 25, 6^2 = 36, 7^2 = 49, and 8^2 = 64.

(16)

Pattern:
A → 1, B → 3, C → 5, D → 7, E → 9, ?
Answer: 11
Explanation: The numbers increase by 2 for each letter.

Explanation: The letters correspond to their position in the alphabet.

(18)

Pattern:
P → 16, Q → 17, R → 18, S → 19, T → ?
Answer: 20
Explanation: The letters correspond to their position in the alphabet, so after S → 19, T → 20.

(19)

Pattern:
M → 13, N → 14, O → 15, P → 16, Q → ?
Answer: 17
Explanation: The letters follow consecutive order, so Q → 17.

(21)

Pattern:
B → 3, D → 6, F → 9, H → 12, ?
Answer: J → 15
Explanation: The numbers follow a sequence increasing by 3 each time: 3, 6, 9, 12, 15.

(22)

Pattern:
A → 1, C → 3, E → 5, G → 7, ?
Answer: I → 9
Explanation: The letters are progressing in the odd-numbered positions of the alphabet.

(23)

Pattern:
T → 5, U → 10, V → 15, W → 20, ?
Answer: X → 25
