Answer:
B. 135, 45, 15, 5...
Step-by-step explanation:
I'll go in order from 135 using the pattern shown (tᵇ/3)
135 / 3
135 = 120 + 15
135/3 = (120/3) + (15/3)
135/3 = 40 + 5
135/3 = 45
All four answer choices show this, so no elimination yet.
45 / 3
45 = 30 + 15
45/3 = (30/3) + (15/3)
45/3 = 10 + 5
45/3 = 15
A and D show 30 as term 3, so they are out.
15 / 3
15/3 = 5
C shows 2 as term 4, so that is also out.
This leaves B as the correct answer.

Your subtract the first number from the second number and get the value.
Dividing mixed numbers is when you take a mixed number divided by a mixed number and make then fractions. Here's an example:
(Example)~5 1/5 divided by 3 1/3
5x5=25+1=26. 26/5
3x3=9+1=10/3
26/5 divided by 10/3= 26/5 multiplied by 3/10= 78/50
Dividing Fractions is when you turn 2 fractions and make them into a multiplication problem. Here's an example:
(Example)~ 2/3 divided by 4/8
2/3 multiplied by 8/4
2/3 x 8/4= 16/12~ Which turns into 1 4/12
Answer:
Step-by-step explanation:
We have a geometric sequence with:
, 
, and 
Where
Sn is the sum of the sequence
r is the common ratio
is the first term in the sequence
n is the number of terms in the sequence
The formula to calculate the sum of a finite geometric sequence is:
Then:
Now we solve for
