Answer 1

do you recall what your 3 times tables are?

Answer 2

so if you see it from 3 till the 6 is differents of 3 and the same from 6 till the 9 is differents of 3 so and the same from the 9 till the 12 is differents of 3 so .... this sign that the line of n atarted with 3 increasing by 3 so than will be right

3*n because 3*1=3
3*2=6
3*3=9
3*4=12
