1.Which recursive formula fits the following pattern?
50, 25, 12.5, 6.25, 3.125...
A(n+1) = A(n) ÷ 2, A(1) = 50
A(n+1) = A(n) − 2, A(1) = 50
A(n+1) = A(n) ÷ 50, A(1) = 50
A(n+1) = A(n) − 50,A(1) = 50
2.
What does a7 mean?
3.
Write a Recursive and Explicit Sequence for the following pattern.
1, 5, 9, 13, 17...
4.What are the first 5 terms in the following recursive sequence?
A(n+1) = A(n) × 3 A(1) = 2
5.
Which Explicit formula would fit this pattern?
3,7,11,15,19...
*Remember, you can check by plugging in the term numbers to see if you get the correct output*

5. Answer:

3, 7, 11, 15, 19, 23, 27, 31, ect.

Explanation:

Just keep adding four

Answer 2

1) A(n+1) = A(n) ÷ 2, A(1) = 50

2) 7 multiplied by a.

3) 1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, .... (add 4 each time)

4) A(n+1)=A(n) x 3A(1)=2

2, 5, 8, 11, 14

5) 3, 7, 11, 15, 19,... A(n+1)=A(n)+4, A(1)=3
