Answer:
a_1 = 0
a_2 = -1
a_3 = -6
a_4 = -31
a_5 = -156
Step-by-step explanation:
a_n=(5a_n-1)-1
a_1 = 0
to find a2 substitute a1
a_2 = (5* a_1)-1
a_2 = 5* 0 -1
a_2 = 0-1
a_2 = -1
to find a3 substitute a2
a_3 = (5* a_2)-1
a_3 = (5* -1 ) -1
a_3 = -5 -1
a_3 = -6
to find a4 substitute a3
a_4 = (5* a_3)-1
a_4 = (5* -6 ) -1
a_4 = -30 -1
a_4 = -31
to find a5 substitute a4
a_5 = (5* a_4)-1
a_5 = (5* -31 ) -1
a_5 = -155 -1
a_5 = -156
The answer would be B, 18cm
