<p>I’m a little rusty on these. Do they show up often on the SAT, and to what extent?</p>
<p>i.e: Will there be circular permutations/combinations or permutations/combinations with repeating variables? Will there be any complicated sequences?</p>
<p>thanks for any help / info =]</p>
<p>only simple sequences/permutations/combination questions come up on the SAT. If you’re unlucky it might be a #18 question which will be a bit harder. The questions i’ve seen so far for sequences are simple arithmetic sequences that say “2…4…6…8…” what is the 10th term of this sequence?</p>
<p>for permutation they ask questions like, “if joe, ann, and mike are going to sit in 3 seats in the classroom. in how many different ways can they be seated — 3<em>2</em>1 = 6 different ways”</p>
<p>it’s pretty simple but a hard one might come up so practice them well. you don’t want to risk losing 10-20 points because you didn’t practice the concept.</p>
<p>One should probably know all the sequence formulas before taking the SAT. Things will be a lot easier if a related question appears.</p>
