Answer 2

You know, you could just plug in the number(s) into each of the equation(s) you have there and see if it matches the next term in the sequence.

Answer 3

what do you mean?

Answer 4

@kathy0514 We have the series as
\[3, 6, 9, 12, 15, 18\]
Does this look familiar?

Answer 5

yes

Answer 6

Yes, it looks like the table of 3, so this is a hint

Answer 7

If I had
\[3(n-1)\]
I'll start plugging the values of n
n=1
=> 3 x 0=0
n=2
=> 3 x1= 3
and so on
SO the sequence we get is
0, 3, 6, 9, 12....
