Indicate a general rule for the nth term of the sequence when a1 = √3 and r = 2.
1. an = (√3)(2)n+1

2. an = (√3)(2)n-1

3. an = (2)(√3)n-1

4. an = (2)(√3)n+1

Respuesta :

[tex]\bf n^{th}\textit{ term of a geometric sequence} \\\\ a_n=a_1\cdot r^{n-1}\qquad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ r=\textit{common ratio}\\ ----------\\ a_1=\sqrt{3}\\ r=2 \end{cases} \\\\\\ a_n=\sqrt{3}(2)^{n-1}[/tex]
