Difficulty: Easy
Correct Answer: N
Explanation:
Introduction / Context:
Midpoint questions ask for the letter exactly halfway (by index) between two specified letters. We convert “from right” to a left index, then average the positions.
Given Data / Assumptions:
Concept / Approach:
Compute midpoint index M = (8 + 20) / 2 = 14, then map index 14 to its letter.
Step-by-Step Solution:
Verification / Alternative check:
List A1 … N14 … T20; N is equidistant from H(8) and T(20).
Why Other Options Are Wrong:
They are one step off the exact midpoint or outside the H–T interval.
Common Pitfalls:
Forgetting to convert the right index first; always convert then average.
Final Answer:
N
