. A sequence starts with 180, 120, …. If the sequence is arithmetic, create a recursive and explicit formula for the sequence. If the sequence is geometric, create a recursive and explicit formula for the sequence.

Arithmetic Sequence

---- Explicit

--- Recursive

Geometric Sequence

---- Explicit

---- Recursive

Step-by-step explanation:

Given

(a) Assume it is an arithmetic sequence

The explicit formula is calculated using:

Where

So, we have:

Rewrite

The recursive function is calculated using:

-

(b) Assume it is a geometric sequence

The explicit formula is calculated using:

Where

So, we have:

Split

Rewrite as:

The recursive function is calculated using:

-

step-by-step explanation:

15   3/4 / 3 = 5   1/4
