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=

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

they disappear if your absent from to long. i found out that the hard way.
