One term of a geometric sequence is a4=135. The common ratio is r=3. Write an explicit rule for the nth term.
Anni [7]

Answer:

a_{n} = 5 * 3^{n-1}

Step-by-step explanation:

To find the nth term of a geometric sequence, you have the general formula:

a_{1} *r^{n-1}

where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):

135 = a_{1} * 3^{4 - 1}

135 = a_{1} * 3^3

135 = 27a_{1}

a_{1} = 5

Now, we can substitute the first term back in:

a_{n} = 5 * 3^{n-1}

What is 106% of $= to $7.95
ankoles [38]
So, I'm not quite sure what you're asking, so I'll answer it two different ways.
7.95 + (7.95 * 1.06)
7.95 + 8.247 = $16.197

The second way:
1.06n = 7.95
n = 7.95 / 1.06
n = 7.5
106 Percent of $7.50 is 7.95
