So, when we're tasked with things like this, rewriting everything in terms of sine and cosine and combining fractions often trivializes things, so doing just that gives us:
So out expression is 1/cos(x).
The third term of an arithmetic sequence is -8, and the fourth term is -20. What is the second term?
