Just look at the explanation
Step-by-step explanation:
So, since Mr.Nicholson is getting an increase of 3500 per year, that is arithmetic sequence. Also, there would be a difference of 3500 in his annula raise each year.
The 5% raise is geometric sequence, b/c there is a constant increase (or ratio) of .05 ( or 5 percent) in each annual salary.
Hope this helps!
