Answer
Correct Answer: M
Explanation
Introduction / Context:We mix left and right indexing. Convert the right index to a left index, then take the midpoint of the two left indices.
Given Data / Assumptions:
- 20th from left → T (L=20).
- 21st from right → L = 27 − 21 = 6 → F.
Concept / Approach:Midpoint index M = (20 + 6)/2 = 13; identify the 13th letter.
Step-by-Step Solution:
Convert right index to L: 27 − 21 = 6.Average 20 and 6 → 13.L=13 corresponds to M.Verification / Alternative check:Alphabet positions A1 … M13 … T20 show M equidistant from F(6) and T(20).
Why Other Options Are Wrong:They are neighbors of the midpoint or beyond.
Common Pitfalls:Failing to convert from right before averaging; that yields wrong values.
Final Answer:M
