Indicate a general rule for the nth term of the sequence a1 = 2 and r = √3.

pantera1 [17]

It is given in the question that,

$a_{1} = 2, r = \sqrt 3$

Since we have the value of r given, so we have to use the formula to find the nth term of the geometric progression, which is

$a_{n} = a(r)^{n-1}$

Substituting the values of a and r, we will get

$a_{n} = 2( \sqrt 3)^{n-1}$

So the correct option is the third option .
