Step-by-step explanation:
First, we look for a common difference.
-102 - (-122) = -102 + 122 = 20
-82 - (-102) = -82 + 102 = 20
-62 - (-82) = -62 + 82 = 20
There is a common difference, and it is 20.
Since the sequence has a common difference, it is an arithmetic sequence.

g(x) = x2 + 4x + 8= b^2 - 4ac= (4)^2 - 4(1)(8)= 16 - 4(8)= 16 - 32= -16
h(x) = x2 – 12x + 32= b^2 - 4ac= (-12)^2 - 4(1)(32)= 144 - 4(32)= 144 - 128= 16
k(x) = x2 + 4x – 1
= (4)^2 - 4(1)(-1)= 16 - 4(-1)= 16 + 4= 20
p(x) = 5x2 + 5x + 4= b^2 - 4ac= (5)^2 - 4(5)(4)= 25 - 4(20)= 25 - 80= -55
