Arecursive rule for a geometric sequence is a1=49; an=3an−1 . what is the explicit rule for this sequence? enter your answer in the box. an=

Answer :

Explicit rule is

Step-by-step explanation:

A recursive rule for a geometric sequence is a1=49;an=3an−1

First term a1= 49

To get second term, multiply the first term by 3

So common ratio = 3

Explicit rule for geometric sequence is

Where a1 is the first term

r is the common ratio

a1= 49  and r= 3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
