What is the recursive formula for this geometric sequence?–2, –16, –128, –1024, ...

Tatiana [17]

Answer:

$b_n=-2\cdot 8^{n-1}$

Step-by-step explanation:

Denote first four terms of the geometrc sequence as

$b_1=-2,\\ \\b_2=-16,\\ \\b_3=-128,\\ \\b_4=-1024.$

Note that

$b_2=b_1\cdot q\Rightarrow -16=-2\cdot 8;\\ \\b_3=b_2\cdot q\Rightarrow -128=-16\cdot 8;\\ \\b_4=b_3\cdot q\Rightarrow -1024=-128\cdot 8.$

Then the common ratio is

$q=8.$

Therefore, the recursive formula for the geometric sequence is

$b_n=b_1\cdot q^{n-1}\Roghtarrow b_n=-2\cdot 8^{n-1}.$

How do you solve 3.4 times 4.37

tigry1 [53]

A book sold 31,100 copies in its first month of release. Suppose this represents 6.2% of the number of copies sold to date. How

nydimaria [60]

Answer:

501613 books

Step-by-step explanation:

6.2% of x is 31,100

6.2%=6.2/100=62/1000

(62/1000)*x=31,100

x=31,100/(62/1000) [divide both sides by 62/1000]

x=501612.90=501613 (rounded up)

Hope this helps!
