Write a recursive and explicit formula for the following sequences. 1) -4, -8, -16, - recursive: explicit: 2) 320, 80, 20, recursive: explicit: find the 7th term 3) 10, 40, 70, recursive: explicit: 4) 4, 7, 10, recursive: explicit: find the 11th term.

1) -4, -8, -16, -32...

Recursive Formula: f(1)=-4, f(n) = 2*f(n-1)

Explicit Formula: f(n) = -2ⁿ        where n>1

11th term = f(11) = -2¹²=-4096

2) 320, 80, 20, 5...

Recursive Formula: f(1)=320,  f(n) =f(n-1)/4

Explicit Formula: f(n)=320/4ⁿ⁻¹

11th term = f(11) = 320/4¹⁰ =

3) 10, 40, 70, 100...

Recursive Formula: f(1)=10, f(n)=f(n-1)+30

Explicit Formula: f(n)=10+30(n-1)

11th term = f(11) = 10+30(10) = 310

4) 4, 7, 10, 13...

Recursive Formula: f(1)=4 and f(n)=f(n-1)+3

Explicit Formula: f(n)=4+3(n-1)

11th term = f(11) = 4+3(10)=34

the answer is a

step-by-step explanation:

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
