Answer:
Part A


Part B
Geometric Sequence
Part C
1/4,3/4,5/4,7/4,9/4

Part D:

Step-by-step explanation:
By definition, an Arithmetic Sequence holds the same difference between each following number.
Part A

<u>Explicit Formula</u>
To write an explicit formula is to write it as function.

<u>Recursive Formula</u>
To write it as recursive formula, is to write it as recurrence given to some restrictions:

Part B

Geometric Sequence, since 2*2=4 8*2=16 and 16*2=32 and 8+2=10 8+16=24
Part C

Arithmetic Sequence, difference

<u>Explicit Formula:</u>

<u>Recursive Formula</u>

Part D
(1.1,1.5,1.9,2.3,2.7) Arithmetic Sequence, difference d=0.4
<u>Explicit formula</u>

<u>Recursive Formula</u>

Answer:
second option
Step-by-step explanation:
Given
f(x) = (x - 7)(x + 4)(3x - 2)
To find the zeros let f(x) = 0, that is
(x - 7)(x + 4)(3x - 2) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 4 = 0 ⇒ x = - 4
3x - 2 = 0 ⇒ 3x = 2 ⇒ x = 
zeros are x = - 4, x =
, x = 7
