The Nth Term Of A Geometric Sequence Is 4/3.If The First Term Is 1/48 And The Common Ratio Is 2, What Is N?
the nth term of a geometric sequence is 4/3.if the first term is 1/48 and the common ratio is 2, what is n?
an=4/3
a1=1/48
r=2
Formula:
an=a1(r)^(n-1)
4/3=(1/48)(2)^(n-1)
1/48(2)^(n-1)=4/3
Divide Both side by 1/48
2^(n-1)=64
log(2)^(n-1)=log(64)
n-1=((log)(64))/((log)(2))
n-1=6
n=7
