Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2.5
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 2.5
The recursive formula allows any term in the sequence to be found by adding d to the previous term, thus
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2.5 ← recursive formula with a₁ = 3
