Question

Consider the geometric sequence: 3, 15, 75, 375, 1875 ... 1. What is the constant ratio, r, for this sequence? 2. Use r to write the explicit formula for the sequence. 3. What type of function does the formula represent? What is its base?

Answer 1

R= 5

$a_{n} =3* 5^{n-1}$

Answer 2

Answer:

1.  r=5

2.  a_{n} =3*5^{n-1}

3. It is an arithmetic function. The base is 3
