First term:

Given; no need to do any work here


Second term:

Replace every n with 2

Replace a1 with -5 (see above)


second term = 7


Third term:

Replace every n with 3

Replace a2 with 7 (see above)

third term = -4


Fourth term:

Replace every n with 4

Replace a3 with -4 (see above)


fourth term = 8



Summary:
First term = -5
Second term = 7
Third term = -4
Fourth term = 8

The first four terms are: -5, 7, -4, 8
