What are the first two terms of the sequence defined recursively by the formula
an=(an-1)^2+4 when a4=1604
a. 2, 8
b. 6, 40
c.
d.

C.  

Step-by-step explanation:

Given formula

when

Substitute n=4 in th given formula , we get

Substitute n=3 in the given formula, we get

Substitute n=2 in the given formula, we get

Thus, the first two terms of the sequence=

is there any attachment? what are the equations?

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
