Answer:

#-14,-17,-20#

Explanation:

#"the terms of an arithmetic sequence are"#

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

#"where d is the common difference between each term"#

#d=a_2-a_1=a_3-a_2=....=a_n-a_(n-1)#

#"here " d=-5-(-2)=-3#

#"to obtain the next term in the sequence,"#
#"subtract 3 from the previous term"#

#rArr-11-3=-14#

#-14-3=-17" and " -17-3=-20#
