Answer:
Twice a certain number is tripled:
2*x*3
= 6x
The sequence is given by the rule

.
This means that the first, second and third terms of the sequence,

, are as follows:


.

.
Now, we can clearly see that 10-6=6-2 = 4. The sequence is arithmetic since the difference between two consecutive terms is the same.
We can also clearly see that the common difference is 4.
Remark: even without computing 2, 6, 10 above, we could see that each term contains one more 4 than the previous term. This is the only thing that changed, while 2 remained "intact".
Answer: Arithmetic; common difference d=4.
