First term: 6
Ratio: 1024
N= 9

no.... common ratio = next term/ previous term a1 and a6 are not consecutive terms

you'd find common ratio =r by, an = a1 r^{n1} here, and only for this, n=6 a1=6 always an=a6 =6144

InsanelyChaoticBest ResponseYou've already chosen the best response.1
so n = 6 temporarily?

hartnnBest ResponseYou've already chosen the best response.1
yes, only to find the value of 'r'

you mean you want next step ? or right side of same step ?

can you find 'r' from that ?

yes let me try

1024^5 = 1.1258999e+15
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
its 1024 =r^5 not 1024^5
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
\(1024 =r^5 \) taking 5th root on both sides, \(\large r= \sqrt[5]{1024}=..?\)
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
try this : \(r^5=1024=2^{10} \\ r^5= (2^2)^5 \implies r=2^2=4\)
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
good! so, now we have r=4 a1=6 n=9 find an ?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
you can use that link.... or the formula
 one year ago

InsanelyChaoticBest ResponseYou've already chosen the best response.1
okay:) Ratio = 4?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
yes, common ratio = r= 4 is what we found out.
