Answer:
Therefore, the first three term of the sequence is:
Hence, the sequence is:
Step-by-step explanation:
Given the nth term
The first three terms can be obtained by putting 
and 
respectively in the given nth term
Putting 
to get the first term
Putting 
to get the second term
Putting to get the three term
Therefore, the first three term of the sequence is:
Hence, the sequence is:
Only -3 satisfies this equation. so i think it has only one solution! hope it will help you..
Answer:
let the price of a pen be x
9 pens cost 7.20, so 9x costs 7.20. Therefore,
