Question 7 (2 points) Use the initial term and the recursive formula to find an explicit formula for the sequence an. Answer is in simplest form.

a1=–3
an=an−1−2
Question 7 options:

an=–3n−1

an=−3n−2

an=−2n−1

an=−2n−3

an=−2n−5

an=–3n−5
Question 8 (2 points)
The explicit rule for a sequence is given.

an=−4(12)n−1
Select the recursive rule for the geometric sequence.

Question 8 options:

a1=12; an=−4an−1

a1=12; an=4an−1

a1=−4; an=12an−1

a1=4; an=12an−1

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer

the cost of the apple depends on the weight

i think it would be 42cm

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
