Activity 2: I'll Tell You What You Are Directions: In the previous activity, you learned the basic concept involving geometric
sequence. Identify which of the following sequences are geometric. If the given is
a geometric sequence, write G and identify the common ratio (r) while N if it is not.

Example:
1.) 1,2,4,8,... G; r= 2 (r = 2)
2.) 3, 12, 48, ... G; r=4 (r = 4)

1. 2, 6, 18, 54, ...
3. 2, 7, 12,17,...
4. 2, 10, 50, 250, ...
5. 5, 7, 10, 14, ...
