Determine whether each sequence is arithmetic or geometric. Sequence 1: –10, 20, –40, 80, ... Sequence 2: 15, –5, –25, –45, ...

ASequence 1 is arithmetic and Sequence 2 is geometric.

BBoth sequences are geometric.

CSequence 2 is arithmetic and Sequence 1 is geometric.

DBoth sequences are arithmetic.

sequence 2 may be arithmetic because -20 but I can't find out what sequence 1 is
