Best ResponseYou've already chosen the best response.0In a geometric sequence, each term is the term before it multiplied by some number. So if that number is r, then find r if 4*r = 8 Figure out what number that is then multiply that number by the last term to get the next.

Best ResponseYou've already chosen the best response.0what times 4 = 8? 4 * 2, right? So as you see with each term, 8 * 2 is 16 16*2 is 32 So we figured out the pattern! Now just multiply 32 by 2 to find the next term.

Best ResponseYou've already chosen the best response.0No problem :) Whenever you have alternating signs in a geometric series, that means that r is negative!

Best ResponseYou've already chosen the best response.0Remember that in a geometric series each term is the term before it multiplied by a number. Just figure out what number that is then find the next term. So 40*that number=100 what number would you multiply by 40 to get 100?
