If a_(1)=3 and a_(n)=(a_(n-1))^(2)-1 then find the value of a_(3). Answer:

Calculate a_(2): We are given that a_(1) = 3. To find a_(3), we first need to find a_(2) using the recursive formula a_(n) = (a_(n-1))^2 - 1. Calculate a_(2) using a_(1) = 3: a_(2) = (a_(1))^2 - 1 a_(2) = (3)^2 - 1 a_(2) = 9 - 1 a_(2) = 8Calculate a_(3): Now that we have a_(2) = 8, we can find a_(3) using the same recursive formula. Calculate a_(3) using a_(2) = 8: a_(3) = (a_(2))^2 - 1 a_(3) = (8)^2 - 1 a_(3) = 64 - 1 a_(3) = 63

Q. If

a_{1}=3

and

a_{n}=\left(a_{n-1}\right)^{2}-1

then find the value of

a_{3}

\newline

Answer:

Calculate $a_{2}$ : We are given that $a_{1} = 3$ . To find $a_{3}$ , we first need to find $a_{2}$ using the recursive formula $a_{n} = (a_{n-1})^2 - 1$ . $\newline$ Calculate $a_{2}$ using $a_{1} = 3$ : $\newline$ $a_{2} = (a_{1})^2 - 1$ $\newline$ $a_{2} = (3)^2 - 1$ $\newline$ $a_{2} = 9 - 1$ $\newline$ $a_{1} = 3$ $0$
Calculate $a_{3}$ : Now that we have $a_{2} = 8$ , we can find $a_{3}$ using the same recursive formula. $\newline$ Calculate $a_{3}$ using $a_{2} = 8$ : $\newline$ $a_{3} = (a_{2})^2 - 1$ $\newline$ $a_{3} = (8)^2 - 1$ $\newline$ $a_{3} = 64 - 1$ $\newline$ $a_{3} = 63$
