Option 4: 15 is the right answer

Step-by-step explanation:

Given

$t_1 = 5$

The recursive formula for given sequence is:

$t_{n+1} = 3.t_n$

This means that the previous term can be sued to find the next term

So in order to find the 2nd terms i.e. t2

$t_{1+1} = 3.t_1\\t_2 = 3.5\\t_2 = 15$

The second term is 15

Hence

Option 4: 15 is the right answer
