What are the first two terms of the sequence defined recursively by the formula a_(n)=(a_(n-1))^2+4 when a_(4)=1604 2,8 6,40 sqrt (2),6 sqrt (6),10

Question

Answer 1

To find the first two terms of the sequence, we need to work backwards from the given term

using the recursive formula

.Let's start by finding

:

Now, let's find

:

Therefore, the first two terms of the sequence are

and

. So, the correct answer is:6, 40
