Answer : 2. "9801"
Explanation :

Answer: B) 9801 Explanation: Clearly, alternatively we add and subtract 10% of a term to obtain the next term of the series.Thus, 10000 + (10% of 10000)= 11000; 11000 - (10% of 11000) = 9900; 9900 + (10% of 9900)  = 10890; 10890 - (10% of 10890) = 9801. 9801 + (10% of 9801)  = 9801+980 = 10781.So, missing term = 10890- (10% of 10890)= 9801.
