Using the sequence:
-4, -16, -64, -256
Write :
Explicit Formula: _______________
Recursive Formula:______________
If you wanted to find the 6th term of the sequence which
equation can you use?
If you wanted to find the 100th term of the sequence which
equation would you use?
Write an explicit rule for each recursive rule.
a. a1 = 25, an = an − 1 − 10 b. a1 = 19.6, an = −0.5an − 1

Write a recursive rule for each explicit rule.
a. an = −2n + 3 b. an = −3(2)n − 1
Write the first six terms of the sequence. 1. a1 = 0, an = an − 1 − 8 2. a1 = −7.5, an = an − 1 + 2.5
3. a1 = −36, an = an − 1 4. a1 = 0.7, an = 10an − 1

One of the most famous recursive sequences is
The Fibonacci Sequence
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
Find the next 3 numbers in the sequence
hint...it's neither arithmetic or geometric
Can you write the recursive formula?
