arithmatic/geometric series

Members don't see this ad.

if you already took the dat,
were there any geometric or arithmatic series questions, since the QR section is evolving, i am studying from sat book and it has a bunch of formulas about this topic to memorize,
is it safe to memorize them (i really don't want to), or am i wasting my time?? they're really easy to apply (that's why i think they might be on the test) but just takes too much time to memorize the formulas,

the types of questions are like: find the nth term, what's the sum of the geometric series, what's the sum of arithmatic sequence,...

i was not successful with the search so plz help me out thanks

What kind of formulas? I would for sure memorize the major ones (areas, circumference, volume) and some trig identities.

this is what I am talking about,









another question, do these formulas qualify as "statistics"?

 

[113zami]

anyone, please???
no one recognizes these formulas?? usually a set of numbers is given with the question

I haven't come across anything like that in any of the practice tests. If you have destroyer, there's a formula sheet at the beginning of QR. I just added a few things to it, like a trig table, and that's worked well for me.
