<p>In the sequence above, the first term is 5 and the second term is a. Each term after the second is the product of the two immediately preceding terms. If a < 0, what is the 10th term of the sequence?</p>

<p>This is a simple question. If a < 0, then a = -1.
b = -5 because 5 x a = -1 = -5.
-5 x -1 = 5, which is the fourth term. Keep following the rule until you get to the 10th number.
Something logically sequential like this on the Math section usually can't be done without a calculator unless you want to proceed slowly and run out time at the end.</p>
