Best ResponseYou've already chosen the best response.1Ok, the equation looks like this: \[S _{n}=a _{1} \frac{ 1r ^{n} }{ 1r }\]

Best ResponseYou've already chosen the best response.0what's S, A, R, and N?

Best ResponseYou've already chosen the best response.1S= the sum n=the term that you choose, so for this example it would be 6 \[a _{1}\]= the first term

Best ResponseYou've already chosen the best response.0So exactly how would you set it up? thats all I need to know, can you show me an example?

Best ResponseYou've already chosen the best response.1Let's break it down a little bit, so it's not so much to take in. We just fill in what we know so: \[S _{6}= 4 \frac{ 1(6)^{6} }{ 1(6)}\]

Best ResponseYou've already chosen the best response.1I forgot to tell you that we get "r" by 24/4=6 because that's our ratio.

Best ResponseYou've already chosen the best response.0This equation does not work @Meehan98 If you try to do for the second term (S2), will hit as the number 20, which is not consistent with the case

Best ResponseYou've already chosen the best response.0Lol but all the information is informant of you _ and the way you get the answer doesn't matter as long as you don't cheat,show work,and get the right answer

Best ResponseYou've already chosen the best response.0Ps I never actually got the answer But I did give you the next numbers of the sequence

Best ResponseYou've already chosen the best response.1hmm..this doesn't make sense then. I've been doing these problems all day without an issue..

Best ResponseYou've already chosen the best response.0ok do it your way ill do it my way _ honestly ever herd of doing it in different methods forget it

Best ResponseYou've already chosen the best response.1I know; because the formula that I have up there is the Sum Formula so it wouldn't make sense to fit the second term in there. The formula for the terms is:\[a _{n}=a _{1} r ^{n1}\]

Best ResponseYou've already chosen the best response.0If you get the second number and divide by the first, will result 6. If you made the third number and divide by the first, will result in 36, which is 6 ^ 2, we can quickly realize the equation, that is: \[n = 4 x (6^{(n1)})\] where: n = number wish to find So, \[n1= 4 . (6^{11}) = 4 . (1) = 4\]\[n2= 4 . (6^{21}) = 4 . (6) = 24\]\[n3= 4 . (6^{31}) = 4 . (36) = 144\]\[n6= 4 . (6^{61}) = 4 . (46656) = +186624\]
