f(n) = 25(4)^n-1

1. Geometric, common ratio of 1/4

2. Geometric, common ratio of 4

3. Arithmetic, common ratio of 25

4. Arithmetic, common ratio of 4

Answer 1

• 2. Geometric, common ratio of 4

Explanation:

Given is the exponential function which is a geometric sequence

It has common ratio of 4

Correct answer option:

• 2. Geometric, common ratio of 4
