Answer:
[tex]a_{n}[/tex] = 3n + 4
Step-by-step explanation:
The terms of the sequence form an arithmetic sequence with n th term
[tex]a_{n}[/tex] = a + (n - 1)d
where a is the first term and d the common difference
d = 10 - 7 = 13 - 10 = 3 and a = 7, hence
[tex]a_{n}[/tex] = 7 + 3(n - 1) ← distribute and simplify
= 7 + 3n - 3 , hence
[tex]a_{n}[/tex] = 3n + 4
