Algebra-1

1. Identify the First Term

The first term of the sequence is:

f(1) = 17

 

2. Calculate the Common Ratio

To confirm the common ratio, we can divide each term by its preceding term:

This shows that the common ratio r is indeed 3.

 

3. General Formula for a Geometric Sequence

A geometric sequence can be expressed with the formula:

Where:

a is the first term,

r is the common ratio.

 

In our case:

a = 17 (the first term)...
