ANSWER

B. –4, –3, 0, 5

EXPLANATION

The general formula for the sequence is:

[tex]f(n)=n(n-2) - 3[/tex]

To find the first term we substitute n=1

[tex]f(1)=1(1 - 2) - 3 = - 4[/tex]

To find the second term, we substitute n=2

[tex]f(2)=2( 2-2) - 3 = - 3[/tex]

To find the third term,we put n=3;

[tex]f(3)=3(3-2) - 3 = 0[/tex]

To find the fourth term, we put n=4

[tex]f(n)=4(4-2) - 3 = 5[/tex]
