To determine the first five terms of the Geometric sequence-
a1=120,ak+1=13ak

Answer to Problem 53RE
Thefirst five terms of the Geometric Sequence are 120,40,403,409,4027 .
The Common ratio is 13 .
The nth term is 120(13)n−1 .
Explanation of Solution
Given:
Sequence - a1=120,ak+1=13ak
Formula Used:
nth term of the Geometric sequence is given as tn=arn−1
Calculation:
Given sequence: a1=120,ak+1=13ak
a2=13(120)a2=40
a3=13(40)a3=403
a4=13(403)a4=409
a5=13(409)a5=4027
The first five terms of the Geometric Sequence are 120,40,403,409,4027 .
Common ratio = r=a2a1
r=40120r=13
The common ratio is 13 .
nth term is tn=arn−1
tn=120(13)n−1
The nth term is 120(13)n−1 .
Conclusion:
Hence, the first five terms of the Geometric Sequence are 120,40,403,409,4027 .
The Common ratio is 13 .
The nth term is 120(13)n−1 .
