In investigating different job opportunities, you find that firm A will start you at $25,000 per year and guarantee you a raise of $1,200 each year whereas firm B will start you at $28,000 per year but will guarantee you a raise of only $800 each year.

Create a sequence for firm A. What kind of sequence is it? Arithmetic? Geometric? Neither? Explain why you believe it is this sequence.

B). Create a sequence for Firm B. What kind of sequence is it? Arithmetic? Geometric? Neither? Explain why you believe it is this sequence.

 25,000, 26,200, 27,400, 28,600, ...
 What kind of sequence is it? 
 It is an Arithmetic sequence
 with a common difference of 1,200.
 B). 
 Create a sequence for Firm B. 
 28,000, 28,800, 29,600, 30,400, ...
 It is an Arithmetic sequence
 with a common difference of 800.

A:  25000, 37000, 49000, ...
It's arithmetic because each term after the first is found by adding the same number to the previous term.

B: same way

C: a(n) = 25000 + 1200n for firm A,  created by adding 1200 times the number of years n to the starting amount

similar for firm B,
