7,4,1,-2 write a recursive and explicit rule for the sequence

recursive:

a (1) = 7 a (n) = a (n-1) - 3

explicit:

a (n) = 7-3 (n-1)

Step-by-step explanation:

for recursive you use a (n) = a (n-1) and then whatever the sequence is. Since yours goes down by 3, it would be - 3 at the end.

For explicit, you use a (n) = first number in sequence+the difference in the sequence (n-1)
