Answer:

[tex]a_{n}[/tex] = 3n + 4

Step-by-step explanation:

The n th term rule for an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 3 , thus

[tex]a_{n}[/tex] = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

Answer:

tn=a+(n-1)d

Step-by-step explanation:

tn=a+(n-1)d

where a=7 and d=3

tn=7+(n-1)3

=7+3n-3

=4+3n
