What are the first three terms of the sequence a1 = 3 and an = 2(an-1)^2? I thought the answer was 3,18,32 but that's not an option! help????

Answers

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\n=2(18^2)\n=648

Like this we can find out any number of terms using this recursive formula
a1=3
a2=2(3^2)=18
a3=2(18^2)=648
