This is a simple ratio question, but first you need to find the number of non red marbles uses... call it a

Jar Tank
54 a
----- ----
1 6750

so using your multiplication skills the number of non red marbles is

Non red = 54 x 9750

thene the total number of marbles in the tank is Red + Non Red

hope it helps

Find the explicit formula for the general nth term of the arithmetic sequence described below. Simplify your answer.

Alexandra [31]

$\boxed{a_{n}=-3+8(n-1)}$

<h2>Explanation:</h2>

The explicit formula for the general nth term of the arithmetic sequence is given by:

$a_{n}=a_{1}+d(n-1) \\ \\ \\ Where: \\ \\ a_{n}:nth \ term \\ \\ n:Number \ of \ terms \\ \\ a_{1}:First \ term \\ \\ d:common \ difference$

Here we know that:

$a_{1}=-3 \\ \\ a_{10}=69$

So, our goal is to find the common difference substituting into the formula:

$a_{10}=a_{1}+d(10-1) \\ \\ 69=-3+d(9) \\ \\ Solving \ for \ d: \\ \\ 9d=69+3 \\ \\ 9d=72 \\ \\ d=8$

Finally, we can write the explicit formula as:

$\boxed{a_{n}=-3+8(n-1)}$

Given the following geometric sequence, find the common ratio:<br><br> {225, 45, 9...}

Tom [10]

Answer:

$\frac{1}{5}$ is the common ratio

Step-by-step explanation:

Common ratio(r) states that the ratio of each term of a geometric sequence to the term preceding it.

$r = \frac{a_2}{a_1} =\frac{a_3}{a_2}........\frac{a_{n+1}}{a_n}$

Given the sequence:

225, 45, 9, .........

Here,

$a_1 = 225$

$a_2 = 45$

$a_3 = 9$ and so on...

Using definition to find r.

$r = \frac{45}{225}=\frac{9}{45}......$

After solving we get;

$r = \frac{1}{5}$

Therefore, the common ratio is, $\frac{1}{5}$
