The first five terms of the sequence are #{0,0,6,24,60}#

To find the first five terms of the sequence #a_n=n(n-1)(n-2)#, put integer values of #n# from #1# to #5# and we get

#a_1=1(1-1)(1-2)=0#

#a_2=2(2-1)(2-2)=0#

#a_3=3(3-1)(3-2)=6#

#a_4=4(4-1)(4-2)=24#

#a_5=5(5-1)(5-2)=60#

Hence, the first five terms are #{0,0,6,24,60}#
