Study the geometric sequence {-4, -84, -1764, -37044, ...}.

Nonamiya [84]

Answer:

$\bold{a_n=(-4)21^{n-1}}$

Step-by-step explanation:

$a_1=-4\,,\ a_2=-84\,,\ a_3=-1764\,,\ a_4=-37044\quad\implies\ \ r=21$

{-84:(-4)=21 and -1764:(-84)=21 and -37044:(-1764)=21}

geometric sequence formula: $a_n=a_1r^{n-1}$

$a_1=-4\quad and \ \ r=21$

$a_n=(-4)21^{n-1}$

Simplify.<br> 3/3-n - n/n-3

Black_prince [1.1K]

$\frac{3}{3-n}- \frac{n}{n-3}= \frac{3}{3-n}-(- \frac{n}{3-n})= \frac{3}{3-n}+\frac{n}{3-n}= \frac{3+n}{3-n}$
