Texaschic nailed it when saying that it's arithmetic
The recursive way to write this is to say


which tells us "start at 6 and each time subtract off 5"
The

portion is the nth term while

is the term just before the nth term

Answer:
2.40
Step-by-step explanation:
From the triangle QRS
RQ is the hypotenuse 13
QS is the opposite = 12
SR is the adjacent = 5
According to SOH CAH TOA
tan <R = opp/adj
Tan <R = qs/sr
Tan <R = 12/5
Tan <R = 2.40
This is indeed a polymomial, it's just not in the correct order. The term with the highest exponent goes first, dictating the degree of the whole entire polynomial. In descending order, the polynomial is written correctly as

. It is a third degree polynomial with a leading coefficient of -2.
