<p>I know it was 2^(last term), but what was the first term of the sequence?</p>
<p>the first term was 2</p>
<p>wait…
if its
2*2^(n-1) its 2^4
if its
2^(2^(n-1) its 2^8
does anyone remember which one it was?</p>
<p>Nevermind… Holy ****, it’s 3 omitted and -2 now. Not a 790, not again…</p>
<p>I got four zeroes for the problem OtherWindow is talking about. But I only remember the four part, not the 2 and 3 (maybe I have bad memory). What were the answers?</p>
<p>@nostalgicwisdom
I know it wasn’t n-1, it was the n-1 term in the sequence</p>
<p>first term: 2
second: 2^2 = 4
third: 2^4 = 16
fourth = 2^16</p>
<p>was there an inequality one where the answer was -2 < x < 1? or something like that</p>
<p>I thought n-1 means whatever it is minus 1.
like if this was the table
n 1 2 3 4…n
term whatever the formula is</p>

Yeah, I think it was like -2<x<-1</p>
<p>It had 4 factors like (x-4)(x-3)(x+2)(x+6) or something and you had to find where it was negative I think.</p>
<p>I recall getting two answers, but only one was an answer choice.</p>
<p>Thanks OtherWindow, can you also explain that question where it was like x+2…something x^3?</p>
<p>yes, I confirm -2<x<-1. -1.5 makes it -</p>
<p>*Wasn’t it -3<x<-1? It asked for which interval contained a solution to (x-4)(x-3)(x+2)(x+6) .</p>
<p>@Mastermind93
I’m not sure which question you are talking about.</p>
<p>@nostalgicwisdom
n-1 means which term it is -1
a(n-1) = the last term (with n-1 subscripted, and I’m not sure which letter designated the sequence, I just always use a)</p>
<p>@Mordred
That couldn’t have been the factors, so we can’t really tell.
look at the graph of that:
<a href=“(x-4)(x-3)(x+2)(x+6) < 0[/url] - Wolfram|Alpha”>(x-4)(x-3)(x+2)(x+6) < 0 - Wolfram|Alpha;
<p>I know those weren’t answer choices…</p>
<p>Can someone make a compiled list?</p>
<p>wow OtherWindow, I’m an idiot. Thanks for clarifying though.
I might have to retake this too. I think I missed anywhere from 6-10(2 of those being omits) :(</p>
<p>Er. Are you sure it included (equation)<0?</p>
<p>yes it did. Mordred I did that problem twice. -4<x<-3 didn’t work. -2<x<-1 did. The rest also didn’t. I’m pretty sure you did the -2<x<-1 choice since you did say you had a -1</p>
<p>Crud, I think I lost my 800. When do scores come out? What was the curve for the January test?</p>
<p>Yeah, I f***** up big time. I might get a 750, but that’s a stretch. O well… October, I guess…</p>
<p>yea i basically ran out of time and had to guess for like 10 questions… assuming out of the 40 i did i got like 2 wrong and 2/10 right out of the 10 i guessed… thats like 10 wrong. what score is that?</p>
