The sequence of the number of chairs in each row is as follows:
- First row: 82
- Second row: 82
- Third row: 82
- Fourth row: 82
This sequence consists of constant terms (all values are 82).
An arithmetic sequence is defined as a sequence in which the difference between consecutive terms is constant. Here, the difference between each pair of consecutive terms (82 - 82) is 0, which is constant.
A geometric sequence is one in which the ratio between consecutive terms is constant. Here, the ratio of each term to the previous one (82/82) is 1, which is also constant.
Since this sequence meets the criteria for both an arithmetic sequence and a geometric sequence, the correct answer is:
C) both
