2/5,2/10,2/20,2/40...
4, 12, 36, 108, ...
–5, 5, –5, 5, ...
Step-by-step explanation:
These 3 sets represent a geometric sequence.
A geometric sequence is a series of numbers where each number is obtained by MULTIPLYING the same fixed number to the previous number.
So, in the first sequence: 2/5,2/10,2/20,2/40...
The multiplying factor is 1/2.
In the second sequence: 4, 12, 36, 108, ...
The multiplying factor is 3
In the 3rd sequence: –5, 5, –5, 5, ...
The multiplying factor is -1.
Most of the other sequences are not geometric sequences, but arithmetic sequences (where the next term is obtained by ADDITION).
