    Seat 1: Peter Seat 2: Lia Seat 3: Kenny Seat 4: Jennie Seat 5: Harvey Seat 6: Joyce Seat 7: Rick Seat 8: Mark

    Step-by-step explanation:

    From Rule 6: Jennie is at Seat 4 and next to Harvey; and by rule 1 (Harvey has a higher seat number than Jennie)

    Seat 4: Jennie Seat 5: Harvey

    From Rule 2: Peter is across from Harvey.

    Since Seat 5 is across from Seat 1

    Seat 1: Peter

    From Rule 7: Peter is next to Lia.

    Therefore, Lia can either be in Seat 2 or Seat 8, but by Rule 3 (Neither Joyce nor Lia is in seat 8), therefore, Lia is in Seat 2.

    Seat 2: Lia

    By Rule 5: Lia is next to Kenny, therefore:

    Seat 3: Kenny

    From Rule 4: Rick is across from Kenny, and Rick is also next to Joyce.

    Seat 7 is across from Seat 3, therefore:

    Seat 7: Rick

    Since Rick is also next to Joyce (and by Rule 3, Joyce cannot be on Seat 8)

    Seat 6: Joyce

    Therefore, we have:

    Seat 1: Peter

    Seat 2: Lia

    Seat 3: Kenny

    Seat 4: Jennie

    Seat 5: Harvey

    Seat 6: Joyce

    Seat 7: Rick

    Since Mark has the remaining seat, Mark is on Seat 8.
