Because we're just adding seven to this arithmetic sequence the twelfth term can be found by multiplying 7 by 12-the current term number and adding that to the current term. [tex]5 \ is \ the \ first \ term \ or \ otherwise \ known \ as \ n = 1
\\ 12-1 \ to \ get \ the \ amount \ of \ terms \ in \ between
\\ 11 * 7 \ to \ find \ the \ amount \ you \ need \ to \ add \ to \ 5
\\ 77 + 5 = 82[/tex]
