Answer: (a)

Explanation:

Given

The pattern is 2, 4, 16, 256...

From the pattern, we can see that the next term is square of the previous i.e.


\Rightarrow 4=2^2\\\Rightarrow 16=4^2\\\Rightarrow 256=16^2
\Rightarrow 4=2^2\\\Rightarrow 16=4^2\\\Rightarrow 256=16^2

So, for the
n^(th) term, the function is
f(n)

For the next term, it is
f(n+1)

So,


\Rightarrow f(n+1)=[f(n)]^2
