In the following exercise, using factorial notation, write the first five terms of the sequence whose general term is given.
$a_{n} = (3 n)!$

Short Answer

Expert verified

The first five terms of the sequence whose general term is $a_{n} = (3 n)!$ are

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegeneraltermsforthesequenceisgivenas \\ a_{n} = (3 n)! \\ Wehavetofindthefirstfivetermsforthesequence. \end{array}$

Step 2. Calculating the terms

$\begin{array}{l} Now, \\ Weknow, \\ 鈬� n! = n (n 鈭� 1) (n 鈭� 2) (n 鈭� 3) ... \end{array}$

localid="1645626806712" $\begin{matrix} n : & 1 & 2 & 3 & 4 & 5 \\ a_{n} : & \begin{array}{l} a_{1} = (3 鈰� 1)! \\ = 3! \\ = 3 脳 2 脳 1 \\ = 6 \end{array} & \begin{array}{l} a_{2} = (3 鈰� 2)! \\ = 6! \\ = 6 脳 5 脳 4 脳 3 脳 2 脳 1 \\ = 720 \end{array} & \begin{array}{l} a_{3} = (3 鈰� 3)! \\ = 9! \\ = 9 脳 8 脳 7 脳 6 脳 \\ 5 脳 4 脳 3 脳 \\ 2 脳 1 \\ = 362880 \end{array} & \begin{array}{l} a_{2} = (3 鈰� 4)! \\ = 12! \\ = 12 脳 11 脳 10 脳 9 脳 \\ 8 脳 7 脳 6 脳 5 脳 \\ 4 脳 3 脳 2 脳 1 \\ = 479001600 \end{array} & \begin{array}{l} a_{2} = (3 鈰� 5)! \\ = 15! \\ = 15 脳 14 脳 13 脳 12 脳 \\ 11 脳 10 脳 9 脳 8 脳 \\ 7 脳 6 脳 5 脳 4 脳 \\ 3 脳 2 脳 1 \\ = 1, 307, 674, 368, 000 \end{array} \end{matrix}$

Step 3. Conclusion

From the above table, we can observe that the first five terms of sequence will be $6, 720, 362880, 479001600, 1307674368000 .$
