You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row
An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row
now use a sum sequence to find total number of seats
Sn = n(a1 + an)/2
Sn = 24(4+119)/2
Sn = 24(123) /2
Sn = 1476 total seats
Answer: 14
Explanation: The radius is half of the value of the circumference.
1, 24; 2, 12; 3, 8; 4, 6. mix and match for the codes but that's like 100+ combinations and I don't have that kind of time sorry
