What is the 300th term of the sequence 57, 66, 75, 84, 93?

a(300) = 2748

Step-by-step explanation:

Each new term is the sum of the preceding term and 9, so that the general term of this arithmetic sequence is

a(n) = a(1) + 9(n - 1).

With n = 300, the 300th term is

a(300) = 57 + 9(300 - 1), or

a(300) = 57 + 2691, or

a(300) = 2748

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
