Find the 6th term of the arithmetic sequence X – 9, -X – 11, -3.3 – 13, ...

MrMuchimi

Answer:

$-13x-23$

Step-by-step explanation:

Given sequence: $x-9, -x-11, -3x-13$

Therefore,

$a_1=x-9$
$a_2=-x-11$
$a_3=-3x-13$

General form of an arithmetic sequence: $a_n=a+(n-1)d$

(where a is the first term and d is the common difference)

To find the common difference, subtract a term from the next term:

$\begin{aligned}d & =a_2-a_1\\ & =(-x-11)-(x-9)\\ & = -x-11-x+9\\ & = -2x-2\end{aligned}$

Therefore,

$a_n & =(x-9)+(n-1)(-2x-2)$

To find the 6th term, input n = 6 into the equation:

$\begin{aligned}\implies a_6 & =(x-9)+(6-1)(-2x-2)\\ & = (x-9)+7(-2x-2)\\ & = x-9-14x-14\\ & = -13x-23\end{aligned}$

Which expression is undefined?

Mkey [24]

Answer:

D: $\frac{3}{(6-6)}$

Step-by-step explanation:

Option A equates to $-\frac{0}{2}=0$

Option B equates to $\frac{(-4+0)}{8}=\frac{-4}{8}=-\frac{1}{2}$

Option C equates to $0\div11 =0$

Option D equates to $\frac{3}{(6-6)}=\frac{3}{0}$ which cannot be defined as division by 0 is impossible
