There are three main types of sequence questions on the ACT and SAT:

1. Those that require the use of formulas to solve arithmetic or geometric sequences.
2. Those that ask you to compute a small-numbered term (such as the 8th term or less).
3. Those that assess your ability to discover a repetitive pattern in order to find a higher-numbered term (such as the 51st term).

It is this third type of sequence--often considered the most difficult by unprepared test takers--that we will address today. Like many ACT and SAT math questions, there is a trick that makes these sequence questions quite easy to solve.

Yeah, hold on to that memory, because thanks to advertising laws, most cereal manufacturers stopped offering such promotions in 2008. I sure wish law makers would at least allow cereal manufacturers to put toys in cereals with low sugar content, as I can't get my twins to even listen to the Snap! Crackle! and Pop! of Rice Krispies. But I guess that's for another blog on another day.

I’ve said it before and I’ll say it again: the writers of standardized tests assess the same concepts, over and over and over again.  Test experts are able to become test experts for that very reason—there is a finite amount of material one needs to learn in order to master the ACT and the SAT. If you study a few dozen tests and find these predictable patterns, you could be an expert, too.
