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
