Directions: In the following question, a letter-number series is given...
The series consists of three elements.
First element (Letter) = The first element in the series is increasing, and the difference between the letters is increasing in continuous odd numbers starting with 1 as shown below.
Q + 1 = R
R + 3 = U
U + 5 = Z
Z + 7 = G
Second element (Number) = The second element is increasing in continuous square number starting from 16 as shown below.
15 + 16 = 31
31 + 25 = 56
56 + 36 = 92
92 + 49 = 141
Third element(Letter) = The third element in the series is decreasing and the difference between the letters is increasing in continuous even numbers starting from 4 as shown below.
F + 4 = J
J + 6 = P
P + 8 = X
X + 10 = H
Hence, the missing term is G141H.

Directions: In the following question, a letter-number series is given...
Series:
The given series consists of a combination of letters and numbers. Let's analyze the pattern in the series to find the missing term.

Pattern:
- The letters in the series follow the pattern of increasing by 3 each time.
- The numbers in the series follow the pattern of increasing by 6 each time.

Analysis:
Let's analyze the given series step by step to identify the pattern more clearly.

Step 1:
The first term in the series is Q15F.
- The letter is Q, and the number is 15.
- The next letter in the alphabet after Q is R, and the next number after 15 is 21 (15 + 6).
- Therefore, the second term in the series is R21.

Step 2:
The second term in the series is R21J.
- The letter is R, and the number is 21.
- The next letter in the alphabet after R is U, and the next number after 21 is 27 (21 + 6).
- Therefore, the third term in the series is U27.

Step 3:
The third term in the series is U27P.
- The letter is U, and the number is 27.
- The next letter in the alphabet after U is Z, and the next number after 27 is 33 (27 + 6).
- Therefore, the fourth term in the series is Z33.

Step 4:
The fourth term in the series is Z33X.
- The letter is Z, and the number is 33.
- The next letter in the alphabet after Z is ?.
- Therefore, the missing letter in the series is ?.
- The next number after 33 is 39 (33 + 6).
- Therefore, the missing number in the series is 39.

Missing Term:
Putting the missing letter and number together, the missing term in the series is ?39?.

Answer:
The missing term in the series is G141H. Therefore, option C is the correct answer.
