a_n=5+2n

Step-by-step explanation:

Each term is 2 more than the previous term, so the common difference is 2.

Let a_n be the nth term of the sequence. Then, the first term is a_1=7.

The second term is a_2=7+2=9, and the third term is a_3=7+2+2=11.

Therefore, every term can be written as

a_n=7+\underbrace{2+2\cdots +2}_{n-1~\text{times}}.

Since repeated addition is multiplication, this can be written as

a_n=7+2(n-1),

which is the nth term rule of the linear sequence.

This could also be expanded to \boxed{a_n=5+2n.}
