Which type of sequence is shown? Check all that apply. 4, 8, 12, 16, . . . The numbers are quickly getting larger, so this is a geometric sequence. The numbers are slowly getting larger, so this is an arithmetic sequence. This is an arithmetic sequence because there is a common difference of 4 between each term. This is a geometric sequence because there is a common ratio of 2 between each term. Add 4 to the last term to extend this arithmetic sequence. Multiply the last term by 2 to extend this geometric sequence.
