Write a recursive formula for the arithmetic sequence below. What is the

value of the 8th term?

1,5,9,13, ...

a. A (n) = A (n-1) - 4; - 27

C. A (n) = A (n-1) + 4; 29

b. A (n) = 4A (n - 1); 29

d. A (n) = - 4A (n-1); - 27

A (n) = A (n-1) + 4; 29

Step-by-step explanation:

From 1 to 5 is 4

From 5 to 9 is 4

From 9 to 13 is 4

then the common difference is 4

then the recursive formula is: A (n) = A (n-1) + 4

1,5,9,13, 17,21,25,29

then the 8th term is: 29
