What is the seventh term of the geometric sequence with a first term of 729 and a common ratio of 1/3?

Question

Arithmetic 

Answer 1

Geometric sequence in general is

 

a_n = a₁r^{(n - 1)}

 

 

Your formula for this condition is

 

a_n = (729)(1/3)^{(n - 1)}

 

 

7th term is

 

a₇ = (729)(1/3)⁶
