Let's take cups of green pepper, onion and salsa to be 3x, 5x and 7x.

In this case, 3x + 5x + 7x = 105

15x = 105

therefore x = 105/15 = 7

cups of tomatoes = 7x = 7 multiplied by 7 = 49

What is the common ratio of the sequence?<br> -2,6,-18,54

aivan3 [116]

<u>ANSWER</u>

The common ratio is -3.

<u>EXPLANATION</u>

In general, the common ratio of a Geometric Sequence is given by:

$r = \frac{a_{n+1}}{a_{n}}$

We can find the common ratio using any two consecutive terms of the geometric sequence by dividing the subsequent term by the previous term.

The given sequence is -2,6,-18,54

Using the first two terms the common ratio is

$r = \frac{6}{ - 2} = - 3$

We could also used the second and third terms to get

$r = \frac{ - 18}{6} = - 3$

and so on and so forth.

Therefore the common ratio is -3.
