UNR    ICF    LEI    OGL    RIO    _____

• A. WTR
• B. UKR
• C. ULS
• D. UJR
• E. UKS

Hint:

For letter-triplet series, analyse each position (1st, 2nd, 3rd) independently. Convert letters to numbers (A=1, B=2...) and find the arithmetic pattern.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This is a letter series with a pattern in each position of the triplets.

Step 2: Detailed Explanation:
1st letters: U, I, L, O, R, ? $\to$ positions in alphabet: 21, 9, 12, 15, 18, ? Differences: $-12, +3, +3, +3$ -- after the initial jump the pattern is $+3$. Next: $18+3=21=$ U.
2nd letters: N, C, E, G, I, ? $\to$ 14, 3, 5, 7, 9, ? Differences: $-11, +2, +2, +2$ -- pattern $+2$ after initial. Next: $9+2=11=$ K.
3rd letters: R, F, I, L, O, ? $\to$ 18, 6, 9, 12, 15, ? Differences: $-12, +3, +3, +3$ -- pattern $+3$. Next: $15+3=18=$ R.
Answer: UKR.

Step 3: Final Answer:
The missing triplet is UKR.
