Best ResponseYou've already chosen the best response.1yes, thats what he is asking. But do u understand the solution given in the old post? u can simply substitute 3/2 by 2/3 to get ur ans...

Best ResponseYou've already chosen the best response.1there is a formula given in the old post on how to calculate the sum....did u see it?

Best ResponseYou've already chosen the best response.0I did, but it's pretty confusing, could you start me out?

Best ResponseYou've already chosen the best response.1u need to understand the 3 terms used in the formula: a, R and n a is the initial term in the series so in this case, it is equal to \[(\frac{ 2 }{ 3})^{11} \] =1 ok?

Best ResponseYou've already chosen the best response.1R is the common ratio...so what is the ratio between the first and second term in this series? Basically what u get if u divide the second term by the first term? u already know the first term, a, is 1...

Best ResponseYou've already chosen the best response.1nope, first term is 1....what is the second term  when n=2....

Best ResponseYou've already chosen the best response.1no, ignore the part that I scribbled out...whatever is left, substitute n=2 and what will u get?

Best ResponseYou've already chosen the best response.1\[(\frac{ 2 }{ 3 })^{(21)}\] = 2/3 So that is R in the formula ok?

Best ResponseYou've already chosen the best response.1n is simple and equal to 4 in this case. So for the formula in the last post, use the following: a=1 R=(2/3) n=4 to calculate the sum. Good luck!

Best ResponseYou've already chosen the best response.1It IS a simple question but I think u have skipped ur study material related to the geometric series. Otherwise u should not have so much trouble :(

Best ResponseYou've already chosen the best response.1not funny :( sorry it is late...I need to go soon. put the values into the last line here: http://assets.openstudy.com/updates/attachments/4fb88e44e4b05565342dc675kelly_011337495416339geometric_sequence_17.gif

Best ResponseYou've already chosen the best response.1sorry to hear about ur health problem but u really need to understand the geometric series first before u can solve problems like this....

Best ResponseYou've already chosen the best response.1Correct! It is \[S = \frac{ (1(\frac{ 2 }{ 3 })^4 )}{ 1\frac{ 2 }{ 3 } }\]

Best ResponseYou've already chosen the best response.1We work it out this time because u found the old post. But you should read up geometric series before taking on more problems like this one.

Best ResponseYou've already chosen the best response.1sorry i need to go now....65/27 is the right ans. good luck!
