It appears that the digit 9 is prepended to each term of the sequence 5^(n-1).
The next two terms will be 5^5 and 5^6, each with 9 prepended: 93125 and 915625.

Answer:
 

Step-by-step explanation:
 Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r 

49+576=

525=c^2 

So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals 

cos=

then we find secant which is the reciprocal of cos so we flip the numbers and that equals
