The third choice is appropriate.
an = 5 - 3(n - 1); all integers n ≥ 1
_____
This equation follows the form for the general term of an arithmetic sequence.
an = a1 + d(n - 1)
where a1 is the first term (corresponding to n=1), and d is the common difference. From the problem statement, a1 = 5 and d = 2 - 5 = -3.
Step-by-step explanation:
let us consider the elevation of the sun is x
then
x=6×6
x=36
"n factorial" is the product of such numbers.
Statements A and C are true
