Pleas help! Several questions listed below: 1. Find a recursive rule for the nth term of the sequence: 7, 28, 112, 448, ... (with steps)
2. Find an explicit rule for the nth term of the sequence: -5, -30, -180, -1080, ... (with steps)
3. Determine whether the sequence converges or diverges. If it converges, give the limit: 9, 27, 81, 243, ...
Converges; 1089
Converges; 360
Converges; 117
Diverges
4. Find the first six terms of the sequence: a1 = 1, an = an-1 + 8 (with steps)
