Question

What is the recursive rule for this geometric sequence?

3,32,34,38,...




a1=3;an=12⋅an−1


a1=32;an=12⋅an−1


a1=12;an=3⋅an−1


a1=12;an=32⋅an−1

Answer 1

The recursive formula for this is the first option or A.

Answer 2

Explanation:

ok so first of all the question is 3 3/2 3/4 3/8

and the answers are

a1=1/2;an=3*an-1

a1=3/2;an=1/2*an-1

a1=1/2;an=2/3*an-1

a1=3;an;an=1/2*an-1 <== and this is the correct one

hope this helps and were your seat belt
