WHAT did I do wrong here? :( What is the 9th term of the geometric sequence where a1 = -6 and a6 = -6,144? First term: -6 Ratio: -1024 N= 9

can i tell you how can you get it ?
-6 divided by (-6144)??
i did this one for you
no.... common ratio = next term/ previous term a1 and a6 are not consecutive terms
wait huh??? then what is???
you'd find common ratio =r by, an = a1 r^{n-1} here, and only for this, n=6 a1=-6 always an=a6 =-6144
so n = 6 temporarily?
yes, only to find the value of 'r'
huh???????????/ ^
don't use that.
plug in values in the formula and use other calculator or google.
I don't know how to get this
what u got after plugging in ?
First term: 625 Ratio: -6144 N= 9
I got numbers that were entirely off
in the 8 millions
8 thousands rather*
= -393,216
ratio is not -6144 ratio = r is what you have to find
ughhhh oh my god
|dw:1363206281770:dw| did you get this step ?
a1=-6 n=6 an=a6=-6144
ohhhh yes yes!!!
what do i do after the -6144
you mean you want next step ? or right side of same step ?
the next step please:)
my notes are progressing!!
|dw:1363206708125:dw| got this ?
-6144/ -6 ?
what is that loop thing?
on right side ? its 'r' r^5
it looks like a deformed male genital
lol :P
ohhhhhhhh!!!!!!! R
yes, r = common ratio
got the step:)
can you find 'r' from that ?
yes let me try
1024^5 = 1.1258999e+15
its 1024 =r^5 not 1024^5
\(1024 =r^5 \) taking 5th root on both sides, \(\large r= \sqrt[5]{1024}=..?\)
let me see
i dont know
try this : \(r^5=1024=2^{10} \\ r^5= (2^2)^5 \implies r=2^2=4\)
got how r=4 ?
good! so, now we have r=4 a1=-6 n=9 find an ?
you can use that link.... or the formula
okay:) Ratio = 4?
yes, common ratio = r= 4 is what we found out.
no...what values you put ?
i got : The 9th term is -393216
I made a few minor errors but i fixed it
great! any more doubts ?
phew! this took an hour!
hahahh so so sorry!!!!!!!!!
you are literally THE BEST
not really, but i'll take the compliment ;) Thanks :D
