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

sorry i need the points

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
