Answer 1

Match Term Definition
2, 4, 6, 8, ... A) Geometric, common ratio is 2
28, 24, 20, 16, ... B) Arithmetic, common difference is -4
2, 4, 8, 16, ... C) Arithmetic, common difference is 2
48, 24, 12, 6, ... D) Geometric, common ratio is 0.5

Answer 3

arithmetic sequence -- the next number can be found by adding
geometric sequence -- the next number can be found by multiplying

2,4,6,8.....looks to me like they are adding 2 to each term to find the next term...because 2 x 2 = 4, but 4 x 2 does not equal 6...you have to have the same difference/ratio between each number
so this would be arithmetic with common difference of 2
understanding this ??

Answer 4

yes thank you!
