Answer: 

<u>Step-by-step explanation:</u>
a) This is an arithmetic sequence where 3 is added to the previous term.
48 + 3 = 51
51 + 3 = 54
54 + 3 = 57
The recursive formula for this sequence is:
*****************************************************************************************
b) This is a geometric sequence where 2.5 is multiplied to the previous term.
100(2.5) = 250
250 (2.5) = 625
625(2.5) = 1562.5
The recursive formula for this sequence is: 
When he cubed ,
Result is x³
On further squaring x³, he got = (x³)²

<h3>Therefore, k =
6</h3>
Since "a" is on the top and the bottom, you can simplify that


Y=-3x+4
slope is -6/2=-3
y-intercept 4
Answer:
1x1
