Which explicit and recursive formulas match the geometric sequence 5,53,59,527,… a. an=5(3)n−1;an=3(an−1);a1=5
b. an=5(20)n−1;an=20(an−1);a1=5
c. an=5(4)n−1;an=4(an−1);a1=5
d. an=5(13)n−1;an=13(an−1);a1=5

:

Step-by-step explanation:

The first term of the geometric sequence is

.

The common ratio between the consecutive terms is

therefore, we see that the nth term is found by

Thus, the recursive formula for the geometric sequence is

1. 22

2. 1

3. 7

4. 18

step-by-step explanation

e2020 got it right

y > 1/3x

y < = -x + 4

hope this : )
