\[a_{1}=-3 and a_{2}=6\]
use the formula : an = a1 r^(n-1) with a1 is given -3 and to get the ratio(r), defined r = a2/a1 = 6/-3 = -2 therefore, an = a1 * r^(n-1) an = -3 * (-2)^(n-1) |dw:1367598379663:dw|
so that's the answer? @RadEn I'm confused

it is not the answer, rather hint as how to solve the problem.
ahhh!! i'm so lost and confused!! @nincompoop
Can you find here the common ratio "r" ??
-2?
Yep..
So, general term can be found as: \[\large \color{green}{a_n = a \cdot r^{n-1}}\]
a = -3 and r = -2.. Plug in and find..
6?
How?
Use that formula,
-3(-2)^n-1?
Yep, this is the general term you require...
okay, but I am stuck here. I dont what is the next step
i get 6^n-1?
Hey, this is the required answer, you can't solve it further..
so this cant get be simplified any more?
No..
\[\large a_n = -3\cdot (-2)^{n-1}\]
okay... how come tho? 6^n-1 looks like an ideal answer to me.
You cannot multiply \(-3\) with \((-2)^{n-1}\)
ohhhhhhhhhhh!!!!!!!!!! duh!! now i get it! my brain hurts been studing all week.
It is okay..
thank you for your time and patience
You are welcome dear..
