Answer is "3" first discover the whole of products of 3 that is 3+6+9+...........+198=Sn1=n(a+l)/2
we realize that last term is 198 so "l" is 198 and an is 3 we need to discover n esteem we realize that
Tn =a+(n-1)d 198=3(n-1)3 n=66 Therefore Sn1=66(3+198)/2 =6633.
Therefore the last answer is 19900-9168=10732.
