Find the 4th term in the sequence with the following definition:

a(1) = 0

a(n) = 2(a(n-1) -3)

tip; (1 , n , & n-1 are to the power below if that makes sense , usually it’d say a^n but there should be an arrow pointing down)

so, a (down arrow) n-1 is my example

the probability that a bird is green (.30) is true

a

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
