Let $d$ be the common difference between terms in the sequence $\{a_n\}_{n\ge1}$ . Then

$a_{19}=-58$
$a_{20}=a_{19}+d$
$a_{21}=a_{19}+2d$
$\implies-164=-58+2d\implies d=-53$

The first term in the sequence, $a_1$ , satisfies

$a_2=a_1+d$
$a_3=a_1+2d$
$a_4=a_1+3d$
...
$a_{19}=a_1+18d$
$\implies-58=a_1+18(-53)\implies a_1=896$

So the explicit formula for the $n$ -th term in the sequence is

$a_n=a_1+(n-1)d\implies a_n=896-53(n-1)$

From the set {80, 19, 11}, use substitution to determine which value of x makes the equation true. 8x = 88 A. none of these B. 1

mel-nik [20]

Answer:

C. 11

Step-by-step explanation:

Substituting, we have ...

8{80, 19, 11} ?= 88

{640, 152, 88} ?= 88

The value from the set that makes the equation true is x = 11.

_____

Alternate methods of solution (other than substitution)

It can be easier to make use of your knowledge of factoring:

8x = 8·11

x = 11

Or to make use of your knowledge of numbers (place value):

8·10 = 80

so x will not be very different from 10.
