Answer:

3,18,648

Step-by-step explanation:

We are asked to find out the first three terms of the sequence.

Recurring formula is given as

a_{n} =2(a_{n-1} ^2)

Since I term = 3

a_{2} =2(a_{1})^2=2(3^2)=18

Applying the same rule,

third term

=a_{3} =2(a_{2})^2\\=2(18^2)\\=648

Like this we can find out any number of terms using this recursive formula
