An arithmetic sequence is defined by the recursive formula t1 = -30, tn + 1 = tn - 4, where n ∈N and n ≥ 1. Which is the general term of the sequence? A) tn = -30 - 4n, where n ∈N and n ≥ 1 B) tn = -30 + 4n, where n ∈N and n ≥ 1 C) tn = -26 - 4n, where n ∈N and n ≥ 1 D) tn = -26 + 4n, where n ∈N and n ≥ 1
