Just plug in n=1,2,3,4,5 for the formula to get the first five terms.
We know that the nth term of the sequence is defined by
a n = n ( n 2 - 6 )
So,
a 1 = 1 ( 1 - 6 ) = - 5 (first term)
a 2 = 2 ( 4 - 6 ) = - 4 (second term)
a 3 = 3 ( 9 - 6 ) = 9 (third term)
a 4 = 4 ( 16 - 6 ) = 40 (fourth term)
a 5 = 5 ( 25 - 6 ) = 95 (fifth term)
Hence, the first five terms of the sequence a n = n ( n 2 - 6 ) are
−5,−4,9,40,95
