Answer:
9 , -9 , -15 , -21
Step-by-step explanation:
6-3x-1=9
6-3x1=-9
6-3x3=-15
6-3x5=-21
The fifth term is 620
y=40×(-2)^(n-1)
The 5th terms means n=5
y = 40 * (-2) ^ (5-1)
= 40 * (-2) ^4
= 40 * (16)
= 640
It makes sense to me but I don't know if anyone else agrees
The equation in standard form is: 3b^2 + 2b - 8.
