please hurry!!
Match a recursive formula for the graph and identify the sequence as arithmetic or geometric.
O Geometric, to = 15 and tn = 2.8+ tn-1 where n ≥ 1. -
O Arithmetic, to = 15 and tn = 2.8+ tn-1 where n ≥ 1.
O Arithmetic, to = 15 and tn = 2.8-tn-1 where n ≥ 1.
O Geometric, to = 15 and tn = 2.8. tn-1 where n ≥ 1.
