Which recursive formula can be used to generate the sequence
below, where f(1) = 3 and n ≥ 1?
3, –6, 12, –24, 48
The recursive formula for this sequence is
f (n + 1) = –2 f(n)
at n=1 f(n)= 3
at n = 2
f(2) = -2 (3) = -6
n = 3
f(3) = -2 (-6) = 12 and so on
Sorry but we need the numbers
Perimeter is , or around 63.89 in.
If you meant that the area was 225 in²:
Perimeter is 60 in
3x - 15 = 105
3x = 120
x = 40
3(40) - 15 + y + 24 = 180
120 - 15 + y + 24 = 180
129 + y = 180
y = 51
Answer:
C: A line travelling to the right with an open dot on p = -3.
Step-by-step explanation:
You use a closed dot when the equation is greater/less than or equal to: 
It goes right because if it went left it would be p < -3.
