Exit Ticket for Lesson #3.12 Consider the geometric sequence given by the recursive rule:
f(1)= 4 and f(n)=f(n-1).
a. Create an equation to find any number in the sequence.
b. Use the equation you created to determine the value of f(3) and f(5).

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

care to share were the trapezoid shown is ?
