QUESTION 10
What will be the missing term of the given series?
A11E, P33L, ___, P27T
Show answer & explanation
Answer: C. K33M
The series follows a pattern where each term has a letter, a number, and another letter. Analyzing the sequence: Position 1 decreases (A→P→?→P), the middle numbers follow 11→33→?→27, and the last letters progress (E→L→?→T). The missing term K33M fits the pattern where the first letter (K) is between P and P in the sequence, the number 33 maintains the numerical progression, and M is the missing letter between L and T.
Step-by-step Derivation:
Break down each term into components:
Term 1: A11E
- Letter 1: A (position 1 in alphabet)
- Number: 11
- Letter 2: E (position 5 in alphabet)
Term 2: P33L
- Letter 1: P (position 16 in alphabet)
- Number: 33
- Letter 2: L (position 12 in alphabet)
Term 3: ??? (missing)
- Letter 1: ?
- Number: ?
- Letter 2: ?
Term 4: P27T
- Letter 1: P (position 16 in alphabet)
- Number: 27
- Letter 2: T (position 20 in alphabet)
Pattern Analysis:
- First Letter Pattern: A(1) → P(16) → ?(middle) → P(16)
Midpoint between A and P: K(11) fits the symmetry - Number Pattern: 11 → 33 → ? → 27
Arithmetic pattern: 11, 33, then 33 (middle peak), 27 (decreasing)
The missing number is 33 (symmetric/middle value) - Last Letter Pattern: E(5) → L(12) → ? → T(20)
Differences: 12-5=7, next should be 12+7=19 or symmetric: M(13) fits as midpoint
M(13) is the center letter between L(12) and T(20) approximately
Answer: K33M (Option C)
