The first three terms of sequence are 9 , 6 , 3
<em><u>Solution:</u></em>
Given the recursive function f(n) = f(n - 1) - 3
Where f(1) = 9
To find: First three terms of sequence
Substitute n = 2 , n = 3 and n = 4 in given recursive function
When n = 2
f(n) = f(n - 1) - 3
f(2) = f(2 - 1) - 3
f(2) = f(1) - 3
f(2) = 9 - 3 = 6
f(2) = 6
Thus second term is 6
When n = 3
f(3) = f( 3 - 1) - 3
f(3) = f(2) - 3
f(3) = 6 - 3 = 3
f(3) = 3
Thus the third term is 3
When n = 4
f(4) = f( 4 - 1) - 3
f(4) = f(3) - 3
f(4) = 3 - 3
f(4) = 0
Thus the fourth term is 0
Thus first three terms of sequence are 9 , 6 , 3
Answer: The required number of ninths needed is 3.
Step-by-step explanation: We are given to find the number of ninths that will after combining together make the amount as 
Let, 'n' be the required number of ninths.
Then, according to the given information, we have
Therefore, required number of ninth needed is 3.
Thus, the answer is 3.
102.444444444 is the answer
Answer= x=100
4/6 = x/150
So you will want to use the cross strategy
6x = 150(4)
6x = 600
6x ÷ 6 = 600 ÷6
x =100
