Solution:
1. Position Andi in the middle seat. There are

seats, so Andi will be in the

3^{rd}

seat.

2. The remaining

friends need to be arranged in the

remaining seats.

3. The number of ways to arrange

friends in

seats is given by

(4 factorial).

4. Calculate

4! = 4 \times 3 \times 2 \times 1 = 24

So, there are

different ways for Andi and her 4 friends to sit in a row of 5 seats with Andi in the middle.
