<p>Can someone just briefly explain how to go about number sequence problems? For some reason they always seem to trip me up a bit, and I guess I just need a simplified way to look at them.</p>
<p>know the formulas for arithemetic sums/series and geometric sum/series. simple as that. know your primes too.</p>
<p>read about taylor's series, and macluarin's series..</p>
<p>as well as binomial expansion</p>
<p>Yeah, but it's just coming up with the formulas that trips me up. I guess I just missed this section in math whenever we did it.</p>
<p>For instance:</p>
<p>3, 5, -5, -3, 3, 5, -5... where each even-numbered term is 2 more than the previous and each odd-numbered term is -1 times the previous</p>
<p>how would i find the 55th term of the sequence?</p>
<p>look for sum patterns</p>
<p>3+5-5-3 = 0</p>
<p>then 3+5-5-3 repeats...</p>
<p>4(13)+3</p>
<p>therefore its -5</p>
<p>alebed01, gimme a break, what is this, the SAT Calculus Killer version 5.0?</p>
<p>Yeah, exactly. The series/sequences questions can just be solving w/ the 4 simple equations (alg/geo sum/seq). SAT tests math up to Algebra II, and isn't Taylor's series part of Calculus AB curriculum?</p>
<p>yeah see above. but taylor and maclaurin and power series are all BC material.</p>
<p>wait, what are the 4 simple equations?</p>
