• A. O
• B. Q
• C. M
• D. P

Hint:

Convert relative positions into absolute indexes and average them to find the midpoint efficiently.

Answer 1

The Correct Option is B

Length of the sequence = 26 letters.
13\textsuperscript{th} letter from left = position 13 = 'W'
4\textsuperscript{th} letter from right = position \( 26 - 4 + 1 = 23 \) = 'T'
Mid-position = \( \frac{13 + 23}{2} = 18 \)
18\textsuperscript{th} letter in the sequence = 'Q'
