A sequence can be an arithmetic sequence or geometric sequence or none.
The true statement is: (d) Both students could be correct. Because two numbers are given in the original sequence, it is possible to find a common difference and common ratio between the successive terms.
<h3>How to determine the student with the correct terms</h3>
The first two terms of the sequence are given as: -5.5, 11
Assume the sequence is an arithmetic sequence, the next two terms would be 27.5, 44.
This is gotten by adding 16.5 (the common difference) to the current terms
Assume the sequence is a geometric sequence, the next two terms would be -22, 44.
This is gotten by multiplying the current terms by 2 (the common ratio)
The above means that: Both students are correct
