Answer:

a_{n}=7n-10

Step-by-step explanation:

Givens

a_{1}=-3\\a_{n}=a_{n-1} +7

The formula to find the iterative rule of an arithmetic sequence is

a_{n}=a_{1}+(n-1)d

Where d=7 and a_{1}=-3, replacing these values, we have

a_{n}=-3+(n-1)7\\ a_{n}=7n-7-3\\ a_{n}=7n-10

Therefore, the right answer is the first choice: a_{n}=7n-10
