A geometric sequence is defined recursively by an = 3an-1. The 1st term of the sequence is 0.25. What is the explicit formula for the nth term of the sequence?

Respuesta :

The 1st term of the sequence is 0.25
and
the common ratio is 3

then:
the 
explicit formula would be:
[tex]a_n=0.25*(3)^{n-1}[/tex]



I hope that helps!
