Five executive team members — P, Q, R, S, and T — are seated in a single row facing North during a board presentation. P is positioned third to the right of S. T sits at one of the extreme ends of the row. R sits immediately to the left of P. Q does not sit at either of the extreme ends. Who occupies the center seat in the row?

The correct answer is P.

Step-by-Step Explanation:

Let us analyze the seating arrangement step-by-step for the five executive team members — P, Q, R, S, and T — seated in a single row facing North (from left to right, positions 1 to 5):

$\text{Total Seats}=5$

$\text{Center Seat Position}=\frac{5+1}{2}=3$

1. Form the continuous block of seated members:
- "P is positioned third to the right of S." This means there are exactly two seats between S and P: S, _, _, P.
- "R sits immediately to the left of P." This places R directly in the seat preceding P.
Combining these clues gives a fixed 4-person block: S, _, R, P.

2. Determine the central position:
- In a row of 5 seats, a 4-person block occupies four consecutive positions.
- Placing the executive team members according to the specified constraints positions P in seat number 3, which is the exact middle of the five-person row.

Therefore, P occupies the center seat in the row.
