Answer:

#12,9,6,3,0#

Explanation:

The general form of an arithmetic sequence is.

#a,a+d,a+2d,a+3d,........... ,a+(n-1)d#

Where a is the first term and d, the common difference.

Note then that each term in the sequence is generated by adding the common difference (d) to the previous term.

#"here " a_1=12#

#rArra_2=12+(-3)=12-3=9#

#a_3=9-3=6" and so on"#
