Answer:
Hello,
Step-by-step explanation:
u(i) is the ith term of the a.s
a is the first term and d the common difference
for n in {1,2,3...}: u(n)=a+(n-1)*d
u(1)=a+0*d=a
u(2)=u(1)+d=a+d=a+1*d
u(3)=u(2)+d=a+1*d+d=a+2*d
...
u(20)=a+19*d

hope it helps
I = 1
II = 1 + 1 = 2
V = 5
VI = 5 + 1 = 6
IV = 5 - 1 = 4
X = 10
A. XVIII = 10 + 5 + 1 + 1 + 1 = 18
B. VII = 5 + 1 + 1 = 7
C. XXVII = 10 + 10 + 5 + 1 + 1 = 27
D. XVII = 10 + 5 + 1 + 1 = 17
Answer: D. XVII
