How to solve 3+5 (c+3)=-17

BlackZzzverrR [31]

3 + 5(c + 3) = -17

First, subtract 3 from both sides. / Your problem should look like: $5(c + 3) = -17 - 3$
Second, simplify -17 - 3 to get -20. / Your problem should look like: $5(c + 3) = -20$
Third, divide both sides by 5. / Your problem should look like: $c + 3 = -\frac{20}{5}$
Fourth, simplify $\frac{20}{5}$ to 4. / Your problem should look like: $c + 3 = -4$
Fifth, subtract 3 from both sides. / Your problem should look like: $c = -4 - 3$
Sixth, simplify -4 - 3 to get -7. / Your problem should look like: $c = -7$

Answer: c = -7

A geometric sequence is defined by the equation an = (3)3 − n.

Delvig [45]

PART A

The geometric sequence is defined by the equation

$a_{n}=3^{3-n}$

To find the first three terms, we put n=1,2,3

When n=1,

$a_{1}=3^{3-1}$

$a_{1}=3^{2}$

$a_{1}=9$
When n=2,

$a_{2}=3^{3-2}$
$a_{2}=3^{1}$

$a_{2}=3$

When n=3

$a_{3}=3^{3-3}$

$a_{3}=3^{0}$
$a_{1}=1$
The first three terms are,

$9,3,1$

PART B

The common ratio can be found using any two consecutive terms.

The common ratio is given by,
$r= \frac{a_{2}}{a_{1}}$
$r = \frac{3}{9}$

$r = \frac{1}{3}$

PART C

To find
$a_{11}$

We substitute n=11 into the equation of the geometric sequence.

$a_{11} = {3}^{3 - 11}$

This implies that,

$a_{11} = {3}^{ - 8}$

$a_{11} = \frac{1}{ {3}^{8} }$

$a_{11}=\frac{1}{6561}$
