Answer:
Geometric sequence.
Step-by-step explanation:
In this situation Mikhail's salary increases by a constant multiple each year. A 3% rate is equivalent to multiplying the previous salary by a constant of 1.03, Mikhail's salary can be modeled by the following recursive equation:
[tex]S_{n}=S_{n-1}*1.03[/tex].
Therefore, since the same multiple can be used to find the next term in the sequence, a geometric sequence best models his salary.
