The explicit rule for a sequence is an=5(−2)^n−1
what is the recursive rule for the sequence?
1) an=−2(an+1)
a1=5
2) an=−5(an+1)
a1=2
3) an=−2(an−1)
a1=5
4) an=−5(an−1)
a1=2

3) ,

Step-by-step explanation:

Given that the explicit rule for a sequence is .

Now we need to find about what is the recursive rule for the sequence and match with the given choices to find the correct choice.

1) ,

2) ,

3) ,

4) ,

Plug n=1 into given formula to get first term

base of the exponent part is (-2) so that means we need to multiply -2 to the previous term to get nth term

Hence correct choice is: 3) ,

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
