Geometric sequence:A geometric sequence is a sequence in which the ratio of any term to the preceding term of that term is always constant.
Common ratio: The ratio of any term to the preceding term of that term.
The 
term of a geometric sequence is represented by 
.
The 
term of the sequence = a.
The sum of first n term is
The common ratio = r.
Given geometric sequence,

Answer:
x=1
Step-by-step explanation:
5x+9 - x= 13
Combine like terms
4x +9 = 13
Subtract 9 from each side
4x+9-9 = 13-9
4x = 4
Divide each side by 4
4x/4 = 4/4
x=1

Answer:
20
Step-by-step explanation:
First we start off with the Pizza ($13)
Then we add our first 2 toppings to our pizza ($2 + $2 = $4)
And then we add our last 3 toppings to our pizza ($1 + $1 + $1 = $3)
Now we can add all of our costs up to get our answer
$13 + $4 + $3 = 20$
Therefore the cost for this Pizza is $20
You have 30 muffins to begin with
24 / <u>4</u> = 30
