Answer 2

Answer:

Geometric

Step-by-step explanation:

7, 14, 28, 56, 112, ...

To check what type of sequence we compare two consecutive terms

14 divide by 7 is 2

28 divide by 14 is 2

56 divide by 28 is 2

112 divide by 56 is 2

the common ratio of two consecutive number is 2

we have common ratio so the sequence is Geometric
