What is the explicit rule for the sequence 3, –6, 9, –18, 36, a. an =2(–3)n–1 b. an =3(2)n–1 c. an =3(–2)n d. an =3(–2)n–1

D.

Step-by-step explanation:

Let's try each rule with some numbers:

Rule A.

Rule B.

Rule  C.

Rule D.

The only rule that has two consecutive values of the sequence when evaluated and starts with 3 is the rule D, first has a 3 and then a -6. It is the rule that generates the most similar sequence.

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7
