Answer
The first five terms are -1, 0, 3, 8, 15.
Work Step by Step
$a_{n}$=$n^{2}$-2n
$a_{1}$=$1^{2}$-2(1) =-1
$a_{2}$=$2^{2}$-2(2) =0
$a_{3}$=$3^{2}$-2(3) =3
$a_{4}$=$4^{2}$-2(4) =8
$a_{5}$=$5^{2}$-2(5) =15
*The 'n' can be replaced with the number of the term you are trying to find. For example, if you are trying to find the 7th term you can plug the number 7 in for 'n'.
