Difficulty: Easy
Correct Answer: T
Explanation:
Introduction / Context:We combine a base letter located by left index with a rightward shift (towards Z). Calculate indices to avoid manual miscounts.
Given Data / Assumptions:
Concept / Approach:Compute L(F) + 14, then identify the letter at that left index.
Step-by-Step Solution:
L(F) = 6.6 + 14 = 20.The 20th letter is T.Verification / Alternative check:Direct count from F across 14 steps ends at T; cross-check with alphabet list.
Why Other Options Are Wrong:They represent other left indices (e.g., R=18, P=16, W=23, U=21).
Common Pitfalls:Losing track mid-count; prefer index arithmetic for certainty.
Final Answer:T
