The ... indicates that the pattern continues indefinitely. The pattern I see is that each term is 4 more than the previous term.
So it's easy to continue, just add 4 to each term to get the next term. But what if you want to know the tenth term without having to go through the ten steps to get to it? Can you find the tenth term in one step? Look at the steps above, The first term is 13. For the second term you added 4. For the third term you added 4 twice (13 + 4 + 4). For the fourth term you added 4 three times and so on
so the tenth term is 13 + 9 × 4 = 13 + 36 = 49. The question was to find the nth term so now I know the nth term is
After all that here is my answer to my question.
