The explicit rule for a sequence is given.
an = 4n − 1
What is the recursive rule for the sequence?
 
A) a1 = 3; an =an − 1 + 4

B) a1 = 3; an = an − 1 − 1

C) a1 = 4; an = an − 1 − 1

D) a1 = −1; an = an − 1 + 4

Thank you to anyone who helps!

Note the series  is

 

3, 7, 11, 15.....

 

So .....the recursive rule is

 

an  = an-1 + 4, a1  = 3  ⇒     first answer

 

 

cool cool cool
