Question

find the common ratio \\(r\\) for the geometric sequence and use \\(r\\) to find the next three terms.

  1. \\(972, 324, 108, 36, \dots\\)

first, identify each term in the sequence. for this sequence,
\\(f(1) = 972\\), \\(f(2) = 324\\), \\(f(3) = 108\\), and \\(f(4) = 36\\)

then, find the common ratio \\(r\\).
\\(r = \frac{324}{972} = \frac{1}{3}\\)

lastly, use \\(f(n) = f(n - 1) \cdot r\\) with \\(r = \text{___}\\) to find \\(f(5)\\), \\(f(6)\\), and \\(f(7)\\).

\\(f(5) = f(4) \cdot \text{___}\\)
\\(f(5) = \text{_} \cdot \text{_}\\)
\\(f(5) = \text{___}\\)

\\(f(6) = f(5) \cdot \text{___}\\)
\\(f(6) = \text{_} \cdot \text{_}\\)
\\(f(6) = \text{___}\\)

\\(f(7) = f(6) \cdot \text{___}\\)
\\(f(7) = \text{_} \cdot \text{_}\\)
\\(f(7) = \text{___}\\)

Explanation:

Calculate the common ratio

$$ r = \frac{324}{972} = \frac{1}{3} $$

Calculate the fifth term

$$ LATEXBLOCK0 $$

Calculate the sixth term

$$ LATEXBLOCK1 $$

Calculate the seventh term

$$ LATEXBLOCK2 $$

Answer:

Find the common ratio \(r\) for the geometric sequence and use \(r\) to find the next three terms.

  1. \(972, 324, 108, 36, \dots\)

First, identify each term in the sequence. For this sequence,
\(f(1) =\) <blank>972</blank>, \(f(2) =\) <blank>324</blank>, \(f(3) =\) <blank>108</blank>, and \(f(4) =\) <blank>36</blank>.

Then, find the common ratio \(r\).
\(r = \frac{324}{972} =\) <blank>\(\frac{1}{3}\)</blank>

Lastly, use \(f(n) = f(n-1) \cdot r\) with \(r =\) <blank>\(\frac{1}{3}\)</blank> to find \(f(5)\), \(f(6)\), and \(f(7)\).

\(f(5) = f(4) \cdot\) <blank>\(\frac{1}{3}\)</blank>
\(f(5) =\) <blank>36</blank> \(\cdot\) <blank>\(\frac{1}{3}\)</blank>
\(f(5) =\) <blank>12</blank>

\(f(6) = f(5) \cdot\) <blank>\(\frac{1}{3}\)</blank>
\(f(6) =\) <blank>12</blank> \(\cdot\) <blank>\(\frac{1}{3}\)</blank>
\(f(6) =\) <blank>4</blank>

\(f(7) = f(6) \cdot\) <blank>\(\frac{1}{3}\)</blank>
\(f(7) =\) <blank>4</blank> \(\cdot\) <blank>\(\frac{1}{3}\)</blank>
\(f(7) =\) <blank>\(\frac{4}{3}\)</blank>
