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"#
