Question

What is the recursive formula for this arithmetic sequence?
-7,-1,5, 11, ...

Answer 1

Answer:

D

Step-by-step explanation:

The recursive formula allows us to find any term in a sequence by adding the common difference d to the previous term.

Here d = - 1 - (- 7) = - 1 + 7 = 6 , then

$a_{n}$ = $a_{n-1}$ + 6 ; a₁ = - 7
