The sequence appears to be decreasing by 9 each time. So, the rule for the sequence is to subtract 9 from the previous term to get the next term. Therefore, the rule is:
a(n) = a(n-1) - 9, where a(1) = 8.
Using this rule, the next few terms in the sequence would be:
a(5) = a(4) - 9 = -19 - 9 = -28
a(6) = a(5) - 9 = -28 - 9 = -37
a(n) = a(n-1) - 9, where a(1) = 8.
Using this rule, the next few terms in the sequence would be:
a(5) = a(4) - 9 = -19 - 9 = -28
a(6) = a(5) - 9 = -28 - 9 = -37
