Write a Formula for the General Term (The Nth Term) $$\mathbf { a } _ { \mathbf { n } }$$

Multiple Choice

Write a formula for the general term (the nth term) of the arithmetic sequence. Then use the formula for $$\mathbf { a } _ { \mathbf { n } }$$ to find $$a _ { 20 }$$ , the 20th term of the sequence.
-Jacie is considering a job that offers a monthly starting salary of $3000 and guarantees her a monthly raise of $190 during her first year on the job. Find the general term of this arithmetic sequence and her monthly salary at the end of her first year.

A) $a _ { n } = 2810 + 190 n ; \$ 5090$
B) $a _ { n } = 3000 + 190 n ; \$ 5280$
C) $a _ { n } = 2810 + 190 ( n - 1 ) ; \$ 4900$
D) $a _ { n } = 3000 + 190 n ; \$ 5090$
