The 4th term of the sequence is -38
Given the following recursive function and,
, we need to get the fourth term of the sequence:
For the second term:
a2 = -2a1 - 2
a2 = -2(4) - 2
a2 = -8 - 2
a2 = -10
For the third term:
a3 = -2a2 - 2
a3 = -2(-10) - 2
a3 = 20 - 2
a3 = 18
For the fourth term:
a4 = -2a3 - 2
a4 = -2(18) - 2
a4 = -36 - 2
a4 = -38
Hence the 4th term of the sequence is -38
